Hey guys I'm almost done with the body on my 51 Chevy pickup, so I started looking around for an engine ****** combo and I found a great deal I'll copy the post so you can see what I'm seeing. 355 sbc freshly rebuild still has to be primed before fired camel hump head been decked n ported 12 to 1 compression big mutha thumper cam Hydro roller lifters roller rockers upgraded studs brand new head bolts intake bolts plenum demon Holley Carburetor 650 headers wrapped Eagle crank race oil pan MSD 6A Blaster 2 coil brand new spark plugs. Rebuilt 700 R4 Transmission with 3200 locking stall. I talked him down to 2500 I guess my question is do I take a great deal and deal with the draw backs of such high compression or spend more on a new package that is more streetable.
What do you plan to do with your truck? do you plan to drive it around? if so, find something else, that's a better "deal".
12 to 1 compression will not be good in a street driven vehicle, look for a better combination and you will never regret it!
Plus I'm not sure where he is getting his compression numbers, I planned to use it for the street mainly. Is there anything that can be done to drop compression. I've talked myself into this I'm just seeing if this really doesn't make sense.
The compression ratio depends on both the heads, and the pistons. He doesn't say what pistons are in it. the heads listed have relatively small combustion chambers, which means higher compression. I like building my own engines, for a specific purpose, using appropriate parts. And, transmissions, too. There's just no way to know what's in them, otherwise.
Cometic makes at least a Dozen different thickness of SBC head gaskets. I just changed some to lower an alcohol race engine to racing gas. I would also ease up on the cam. Would I buy it for that price HELL YES. For less than 500 u will have a great eng/trans combo especially if you do your own work. PM if you decide to do it. Ican figure out how much to go on the gasket if you can give me a little more info.
I guess you're more trusting...when I read an ad that is worded like that, it makes me think of the worst possible engine build....
I'l do that if I do buy it, I've had reservation about not hearing it run but I feel like this is normally a 7500 dollar setup.
If you want a SBC just get s 96-99 Vortec 350 toss the EFI plop a carb manifold and HEI on it and Bam best SBC you can come up with. Back it up with a 700R4 and you are all good to go. Sent from my XT1585 using The H.A.M.B. mobile app
If it were all done properly, it could be a 7500 dollar setup. But it could also be junk. Add up the value of the parts you can see, ***uming they are in no better condition than you can verify by looking at them...maybe it's a good deal.
Unless you like to buy 10 bucks a gallon fuel. You need to look elsewhere or plan on a piston change. even with E-85 that wouldn't work unless you had big chamber aluminum heads.
I hear you squirrel I think the same way you do but I also put the blinders on when it comes to moving my project along.
I'm not much of a roundy-round guy, so have a question. Do they use automatic transmissions for circle track racing?
not like that. It sounds to me like a build by someone who didn't really have everything fully planned out....
7500 seems like a lot for an unfinished sbc . I bought an unfinished motor before and by the time I was done it wasn't a good deal after all because it setup for a blower motor and I needed it more for street.
Never had very good luck buying something that was already done without knowing the person that put it together I've found good deals but just could never pull the trigger on taking someone's word when it comes to one of my motor's So i always had to build my own from scratch cost a little more but at least you know what you have in the end, but that's me and jmo Good luck on which ever way you go 12-1 is two high for the street unless you're going from red light to red light and that case it sounds like fun Sent from my iPhone using Tapatalk
That number was including transmissin and torque converter. As far as the circle track thing I'm think the engine was built to race but figured he could put an overdrive transmissin behind it for the street use
You pays yer money, you takes yer chances. Sin in haste, repent in leisure. I would build or buy what I wanted, not what was just available. And I want to know what I'm getting, not some guy's word.
the price might be a good deal if is set up exactly for what you need/ want - there are too many SBC motors out there that are set up for street use - if your first action will be to de-tune motor/trans you are looking at the wrong "deal" - does seller have recent receipts for all of the work done by a professional shop? I bought a complete rebuilt/ blue printed '65 327 years back from a guy that had receipts to back up his claims, for thousands less than what you are looking to buy - your money, do with it as you like
And don't trust the receipts from "professional shop" unless you can talk to them personally. I'm in the process of re-rebuilding one that I got in a project. Never been started and had the invoice showing all the "right parts". New RHS heads (of course they had 76cc chambers and 230 intake runners), New Lunati "hot street"cam (was parts house stock replacement with NO numbers or markings) New forged flat-top pistons (they were dished rebuilder pistons designed for a block that had been decked) Sat way down in the hole. The combination ended up with CR in the upper 7's. To make a long story short, I have replaced everything except the block and crank. My first and last purchase of a built engine. I go back and forth on who was the liar....the PO or the engine shop. oh yeah.....anybody need all new parts to do a stock rebuild on a 350? cheap!
I know, but he could buy it just for the trans and sell off the engine or rebuild it Sent from my XT1585 using The H.A.M.B. mobile app
