Title: 350 heads and 305 block
Post by: st3vomettler on November 02, 2015, 09:25:40 PM

I am wanting some opinions on a 86 305 block casting number 14088551 and 350 head with casting number 333882.

Ok do you now it it will drop the compression much?

882 heads on a stock 70's 350 run close to 8:1 compression.  On a 305 you can do the math, but I'll bet it's going to drop close to 7:1.  Might be an awesome candidate for ridiculous boost, though!

Ok the Pistons are dish shape but I don't now it that will effect anything.
