My new ride 70 Custom Longbed - The 1947 - Present Chevrolet & GMC Truck Message Board Network

solarnick · 07-24-2012, 04:58 AM

I picked up this truck about 3 months ago. Just been doing all my research on here. The PO had the truck for about 6 months before moving and the new place wouldn't let him have three cars. This had to go. It had a pretty bad knock when I got it. He had post $3000 on craigslist and after hearing it run, I got him down to $2300.

He said that the knock was because the #6 intake stud pulled out of the head. I went to the local picknpull and got another 350, factory AC compressor, and a Th400 for the grand total of $480 from a 71 C20.

I had the picknpull heads refurbished. Upon teardown of my heads, I found the cam lobes were all worn down and the PO just kept tightening the #6 intake rocker bolt to get the lash out until it just pulled it out of the head. More than 12 lobes had at least .25" worn down.

The rest of the block looks great. .030 over pistons already installed, cylinder bores are smooth and clean. At this point I'm just going through all my parts to get a baseline before I fully rebuild it.

My question is.... looking at my Quadrajet, I know I am missing all of the upper plates and choke mechanism. Should I just ditch this one? I've already bought a Edelbrock Performer EPS and Performer cam kit.

Thoughts? Yes that 454 sticker has got to go. I'm pretty happy with what I paid for a pretty clean body. Plans are to eventually bag it.

Welcome aboard from Central Florida (formerly from High Street in Monterey

)
Good looking, well bought truck. I ended up benching my Quadrajet and getting a Edelbrock carb to go with my Edelbrock intake. Woke it right up (402 BB).

First of all solarnick....

to the forums and

from Ohio.

on your new

I think those who own 1970

trucks are

dudes.

As far as carb I have the factory Quad and love it but Edelbrock Performer should be a fine performer also. Kepp us updated to your progress.

welcome to the board from Texas, looks like a real nice truck...good find...if the knock was on top, i think you have the right idea for cam,carb,intake and heads, put it back together and have fun...

Welcome from south Florida and that looks like a real good buy. You'd have a hard time finding one that clean down here for that price. I've never had much luck with Edelbrock carbs, personally like Holley's, but others on here are running Edelbrocks with good results. Good luck, and have fun with it

I've done a few searches on quadrajets. Does anyone sell new parts to make my Quadrajet work? I've only seen a few companies that sell the center shafts and linkages for the choke, but not the plates.

rcbildr · 07-25-2012, 05:14 AM

You could probably find the parts you need in the wrecking yard.

DT1 · 07-25-2012, 09:57 AM

Congratulations on the truck. You really picked up a gem. Why someone would remove the top plates has me baffled.
I noticed you live in Monterey. I bought a home in Pacific Grove that I'm currently leasing out. Some day soon I hope leave the desert and move there.

The quadrajet should still work fine without those parts, it will just be a little harder to start and keep running when cold.
