302 building info

[Guest Nic-Rebel450CA]

Sounds like a decent price, I will definitely give that some thought. I found the specs, not very impresive (200HP at 5000RPM) but definitely a starting point.

 

I also found another topic on a site with this information:

The LT1 lower end is just like the 350.

GM decided to make a 265 (4.3L) V-8 with the reverse cooled heads for the Caprice and Roadmasters.

One option was to start making the 3.75 bore pistons with the 1.785 pin height due to the 3" stroke.

Another option was to increase the rods to 5.94" and use the 305 pistons with a pin height of 1.545"

GM made longer rods so the "L99" has a 3" crank and 305 pistons.

 

With these parts available, a 302 can easily be made with factory components.

The LT1 engines were reversed cooled. (water flows thru the heads, bypasses the intakefold, then the block).

This allow higher compression ratios with 87 octane gas.

A 302 can be built using LT1 350 pistons, and L99 rods and crank.

This will drop the compression ratio from 10.5 to about 9.

Since the L99 came out in '94, it has large journals and a one piece rear main seal.

If lightweight 350 pistons are used, (same weight as the 305's), the crank should be pretty close to balanced.

Light pistons help in the high rev's and thats what the 302 is all about.

This setup is better that the earlier 302's since it is has longer rods giving a r/s ratio of 1.98.

One of these days I will be able to decide what I want to put into my Z...
