Will these fit my 87 3.8 NA block? SBC 350 .100 Dome .020 Over Hi-Compression Pistons & Moly Ring - Edmonton Engine, Engine Parts For Sale - Kijiji Edmonton Thanks.

3.0 will bump your compression up but you have to machine reliefs for the valves in the pistons. Also I read in the Buick Performance Stage book the increase in CR is more like 12:1. The best way to get the CR up is to get the Speedpro Hyper pistons. They will give you 9.5:1 CR which is...

Now when you say the 3.0l piston is this the flat top one or a domed piston. Also what is the exact increase in CR? Thanks Charlief1

No this makes perfect sence. I am using an 87 block and heads tho. Do I still need to do this?

Can you tell me a bit more about this procedure? I've never done it. Thanks.

Thanks for the reply. So these springs should be OK then? I'm using the 204/214 Cam. COMP Cams 980-12 - COMP Cams Valve Springs - Overview - SummitRacing.com

I'm rebuilding my 3.8 carbed N/A peoject and need to know what you guys are suggesting for valve springs. I'm using the Edelbrock kit. Heard something about 105lb springs and 980's but need more info. Please help. Thanks AJ I thought I was posting in B4 black. :confused:
