Hot Rods 283 bored .060

DP carbs came on a 65 327. 4150?
I haven't poured the heads yet, info provided by machine shop. I'm sure I'll come up with a question or two, as I tear it down.
Also may give me some info. I'm curious to know what cam is in there now.
I can't ask the previous owner,as he is deceased. Hard to believe someone takes a 283 bores it .060 with pop-ups and didn't cam it.

 

That's prettygood!

 

I don't think so!
Pretty sure the first oem Chevy with the double pump Holley was 67 Z28 302 and big blocks.

 

No. No, and no.
This is going to come as a shock to some of you younger folks especially .The DP Holley was released in the mid 60's as a high performance replacement .It came stock on..NOTHING.
Probably a good thing, too. Emissions regulations would have been even stiffer.
Frontwards or backwards, all vacuum secondaries:

 

The '68 L88 had an 850 DP, as compared to the '67's vacuum secondary carburetor. Also, the over the counter Trans Am inspired cross ram used (600cfm?) double pumpers.
I think it was 1968 when Holley introduced the DP's as List numbers 4776- 4781, 600 to 850 cfm. Later, in the '70's they also had a few emissions/performance DP's like their Quadrajet replacement carbs.

 

Okay..I knew this stuff would come up.I should have clarified in the beginning.
RPO, showroom available, etc. Not over the counter , dealer options, etc. .
The L 88 was not sold as a street motor.
What this all has to do with vintage looking 283's, I don't know.
We still don't know what the o/p's certain look is that he's striving for. ??
Of course, we spent 3 days last week ,on a 327 pipe dream, so nothing surprises me anymore. LOL

 

Maybe that's a mill al tschida built.....he won '64 c/gas at Indy

My comment was basically directed at the OP's statement as to "dp" Holleys coming out on 65 327's, that is for a fact not true.
I am old enough to remember taking my high school pal to get a used 68 Z28 in 1971.
They also weren't supposed to come with the JL8 four wheel disc brake option in 68 but this one did.

 

I don't mind if people get on this thread and wander off. I'm sure ther is a lot of bench building, too.. I'm getting into motors and hot rods.. sorry, guys I just didn't grow up building motors.
I ask questions, because I don't already know the answer.
Thank you too everyone who had put forth positive info. I appreciate it.

 

Cool story. Wth does this have to do with a built up 283???? So, I'm not a Holley carb tech, and as I've state before in this thread I'm knew at this stuff. If you don't have anything useful to put forth, then move along.
Some of you guys on here just like trolling people's threads.
Some of you have been great and I/we are thankful.

You did say you don't mind people wandering off on your thread.
You are absolutely right though, a lot of us do that, I guess it comes with age.
I'll try and keep the HAMB dry and humorless from now on.

 

It's a 1960 283 that was originally built in about 1968 by a guy in Fairview ILL. At that time is was bored .080 with Jahns 12 1/2 cast pistons. This was with a set of 2.02 fuelly heads, 300 Hp. 327 cam and intake. The carb was a Carter AVS of unknown CFM.

My older brother bought the engine in 1970 and installed it in his 57 Chevy Sport Sedan. At about this time, it got a 375 Hp. 327 cam, and an Edelbrock Tarantula intake. The carb was also changed to a 780 vac. secondary Holley off of a, (then new and newly wrecked), SS 454 Chevelle. By the way, the Chevelle was in a junk yard, (Ace Auto Salvage), in Bartonville ILL. at that time.

I bought the engine and installed it in my 55, in 1977. Currently, it is still basically the same as it was in about 1970. However, I had it bored out to 301, in 1984. The pistons are now TRW factory replacement forged pistons for a 302 Chevy. The compression is 11:1. This machine work was done at D & D Speed and Machine in Peoria ILL. Later, it was freshened up in 1998.

 

I don't think dry and humorless would be any fun! As far as "wandering off"... I did say that, because I was trying to be polite to people who were sharing info on old builds. Listening is a great way to learn.
That's a bit different than some smart a** remark by a person/s who aren't offering anything substantive.
Have a nice day!

 

Thanks man! I appreciate you sharing this info. I enjoy hearing how guys set up their old builds! I'm probably overthinking mine a little.
Thanks again

 

Im looking forward to hearing how your build is going.....please keep us in the loop....with pics !!

 

I definitely will!

 

I don't know if this will be helpful but here's a link to a thread here on the HAMB that shows the block to be from '58-'62 but does not say what model car it could have been from.

Thanks! Not super concerned, at the end of the day, what it came out of. I'm just overly inquisitive about stuff like that, lol!
What I am excited about is the car build!!!
For fun, I'm going to build it like the 300hp/327 L79.
Car is a 39' Chebbie Coupe. I'll post pics as it goes along! Thanks for the link!

 

Some things to think about . . .

Camshafts and valve train components/technology have come a long way from back in the day - some of that has to do with valve spring technology, but also all the various rocker arm packages, roller rocker designs, etc - that didn't exist in the 60's. I like the 461 heads - ran those on quite a few 327's. If it was mine, I'd have the heads street ported (at least good bowl work done), put in high quality pro-flow type valves (Manley), put in 7/16 screw in studs and pushrod guide plates. I'd also run a mechanical roller cam, beehive springs and a quality set of aluminum roller rockers. Having a well built top-end will allow the 292 to breathe and to have a stable valve train at higher rpms.

Once you know your complete package (engine specs, trans and gears, rear end - car weight, usage goals), then give the guys a call at Bullet Racing cams - talk to their experts about exactly what roller cam they'd recommend (along with how much carb). Also ask them what ratio rockers and spring package for the given cam. These guys really do great work, their cams run really well -- street, Bonneville, blown, alky - you name it. You'll like their service and be very happy with the results. Also, to have the old school look, better get yourself a nice Vertex Mag! LOL

 

Early Corvette Pistons. 11.5:1 CR Good Dome... Short Reach Spark Plugs Indexed required or you will close the electrodes.

 

Aron, Did you ever finish this 283?
I'd like to hear what and how...

Looks like the original poster has not been to this site since April 2017.

 

Bummer!

 

Probably sold it and bought a new Camry.
