1967 Chev 302 parts choice question

Rory Christianson · 09-28-2012, 02:34 PM

Was wondering what choice for a block and crank would be best to build a stocker 67 302 chev out of the 67 block and crank had smaller journals and would be getting hard to find and as far I know bearing spacers are not allowed ?
Also wondering the best head casting number for the 67 chev 302 z would be for a stocker ?

Thanks for any help and thoughts in advance

I can't answer your question (except no to spacers) but congratulations on picking such a fun project. I love those high RPM 302's and wish I had one.

Thanks. I already have a project on the go, and then I picked up this old unrestored camaro and got thinking now I don't think I can resist
Thanks again

I think crank spacers are ok in stock, when you use a bowtie or dart block, you need spacers for small journals crank. Tom

Rory, I would contact Dwight Southerland (forum member). He would be a wealth of information on this combo. Hope this helps.

The early 68 Z/28s used the small journal crank & block also, we had one & raced it as a stocker in the early 80s

Mr. Duzac knows a thing or two about this combo.

Duzac and Peterson, the Wenzel brothers ....................................

The thing to do would be to get a small journal BowTie block. No spacers required.

If they are going to allow aftermarket cranks, perhaps Eagle might be convinced to make a small journal 3" stroke crank.

The legal castings are : 462,041,186,492,291

The intake you need is a 3917608

You can use the new Quick Fuel carburetor.

You probably want to pick a cylinder head guy, and have him tell you what heads he wants, then buy 3-4 pairs so he can pick through them.

Welcome to the asylum, and good luck.

Bowtie block with spacer bearings.
A 283 crank is good. Look for forging # 236.
Heads - be careful. There are good heads and there are not-so-good heads. The original big-valve 462 and 291 heads are good. The 041 may have some benefits.
The intake casting is 610; 608 was the part number.

Aftermarket, aftermarket, aftermarket as much as possible.

Thanks again everybody
