So Im kinda hit rock bottom on my budget, i have a standard bore 350 short block i mean its pretty much a new motor, super clean new bearings etc, has a cast crank, stock rods, pistons are stock flat tops with the the 4 little eyebrows on them, i really wanted to build a 301 sbc, but i was sitting in my garage thinking how am i going to get the money, im 17 years old and no job, but i figured you know what im going to throw this motor together with what i got so i can get my 55 chevy on the road (but i want it sorta quick) so this is what i got so far. Stock 350 short block, standard everything excellent shape. Heads are 291 camel humps, minor port work 2.02 valves, screw in studs, guide plates, double springs good to .550 lift they are 64 cc combustion chambers so im guessing my compression ratio will be around 9 to 10:2:1. Cam is a old crane solid roller, here are the specs. Moderate to fair idle, good midrange hp for bracket racing. 3000-6500 Rpm Range 118021 Part Number 234, 244 Deg. Duration @ .050" lift 296, 306 Adv. Duration 112* lobe seperation .022" valve lash hot .500 .500 gross valve lift 1.5 proform roller rockers Not to sure on the intake i might go dual plane or single plane, this is where i want yal to help me decide, Here are my options. Holley contender the (300-06) the best one the made. Holley strip dominator. Old edelbrock torker. Edelbrock victor jr. Weiand Hi-Ram i have both dual and single tops. and i have two 550 holleys to bolt on or a 750 holley double pumper. Edelbrock XC-8 cross ram with the 550 holleys bolted on. Ignition is a mallory dual point with mechanical advance. As stated above are my carb selections. Headman longtube headers. I think thats it, it will have a muncie m-20 4 spd and a 8.5 10 bolt with im thinking with this combo 3.90 to 4.11 gears, so give me yals inputs on the combo.
i would go with a old edelbrock torker single plane you get the best power with high clean RPM's and a holley 650 dubble pump with the 50cc pumps you should come alive and i would go 4degrees advance your cam
Your engine sounds really close to what I had in my '57 wagon.....I ran an old eldebrock TR1X tunnel ram with 2 600 holley's......4-speed and 5.13's with a 33 in. tall tire(pro street car).....very streetable and got 10 mpg at 3300 rpm.....that was about 62 mph....On the track that engine went 8.40's in the 1/8 with mickey thompson's.......with slicks my car ran 7.90's......the car weighs 3540 lbs. without me in it.
Not sure if it's needed for a sbc but check and make sure you have the right distributor gear for a steel roller cam....
You didnt really say what the intended use for the car is.... But its not gonna be a docile cruiser with a single plane, or duals. If you're planning on pounding on it, its gonna be a hand grenade. Sounds like some good parts, but not a good combination.
Yeah its not going to be a cruiser, just a weekend warrior, and maybe drive it from school and back every now and then, it will probably see some track time too.
"Since its a older cam it needs a steel gear, so i have it, a lot of the newer rollers take a bronze" Is it just me or is the above statement completely backwards. I thought the older cams required a bronze gear and that some of the new solid roller cams don't require them because of a pressed on cam gear.
Well i do have a edelbrock tr1yx tunnel ram the problem with that intake and the reason i dont want to use it, is that i have to run the carbs side ways and i really dont want to be looking around for the linkages, my dad is also running that tunnel ram on his 55 chevy the orange one in my avatar, also i have a offenhauser turbo thrust 360 tunnel ram, the one with the dividers, the problem with that one is it is too tall it hits right on the firewall with holleys so the only carbs i can run with that intake would be edelbrocks or old AFB's.
I think you are wrong on that one. Solid roller cams are made of billet steel and require a bronze distributor gear. However, some of the newer cams, although still billet steel, use a pressed on cast dist drive gear so a regular dist gear can be used. Yeah, you might want to look into it to make sure (I could be wrong) .
Don't get all hung up with how you want the engine. Just get it on the road and build another one later. Changing engines is nothing.
Run the Victor Jr. and dump the Pro-Form rockers they are known to have cracking issues, for about the same price use stainless steel rockers or Scorpions if you go aluminum.
Ahh, to be 17 again. I remember spending every paycheck at the machine shop trying to build the baddest small block I could afford. Sportsman II heads, built th400, stall converter, and cheap was never an option. I wanted to be kill of the hill. looking back, a crate motor would have been better for me. patience and a teenage hot rodder never seem to mix.
Mine were mounted inline and the windshield wiper motor had to be taken out for the t-ram to fit......but it runs really well though.......Here the specs on my cam... Adv. duration intake: 282 Adv. Duration exhaust 292 Duration@ .050 intake: 250 Duration @ .050 exh:259 Valve lift Intake: .508 Exhaust .525 Lobe Separation: 108 Intake centerline 104 Lash Setting intake: .18 Exhaust .020 RPM Range Advertised 3800-7000
Before you start p***ing out engine advice, do an intro. It is not about what you know, it is the house rule. Punctuation and capitalization will also go a long way toward us being able to understand what you are trying to say.
What he said, every part effects another part and sometimes works against itself and you end up with a lot of money in a motor that won't keep up with a well tuned stock small block. Take small steps. The cam, The carb, The timing (good luck and have fun)
What brand of cam is that? is it a solid roller? And well i dont plan on running the wiper motor nor windshield wipers. The car isnt going to have a hood, inner fender wells, and no lower valence, just the fenders, grille, and radiator support.
I would love a set of sportsman II heads, yeah im always thinking of different combos, i think its time to quit day dreaming and throw this motor together, i mean i have a ton of motors to play with from 283's to 327's to 400 sbc's to 396's to 454's its just its going to cost more to build those then this motor, and im hoping to get this car painted and most of the mechanical work done by the summer.
Ok im not trying to be a jerk or anything like that i just want to clear something up, why the victor jr? People say dual plane is the way to go, that ill lose more low end torque if i go with a single plane, my question is there a big torque loss as everyone says with going with a single plane? Or is it just bs lol.
the cam you want to run says use the victor, but if your on the street a dual plane is hard to beat for low end torque . are you running power brakes?
Nope no power brakes, no a/c, no power steering, this car is only going to have a front seat, bench to be exact, the rest is going to be gutted, just carpet and a roll bar, basically a race car look, but im going to drive it on the street, not a daily just something to go to the local hangouts, and it will see a little strip time for fun of course i dont expect a 10 sec car lol.
proper tuning of the carb(s) will be more important than who cast the tunnel ram/ single plane /trick of the week intake. with that top end race car cam, it needs to be just right.
On the intake I would run with the Holley Contender for sure. I got one now perfect drive it to the strip run it hard and drive it home intake. Good flat power curve. At least it works well in conjuncton with the rest of the parts used to ***emble my particular engine.
