big block blazer

Hello,

I have some questions about installing a big block buick into my 1990 s-10 blazer. I already have a sbc in it and I am looking for some more torque. First off, I will say I am on a limited budget and am trying to do this as cheap as possible. I got the 430 buick out of a 68 riv and I am trying to install it in my blazer, but as would be obvious, I am having some trouble with it fitting. I am pretty capable as far as modifications go. I am absolutely addicted to torque and I love the big block buicks because they are only slighly larger than a small block chevy and only about 25lbs. heavier in full iron trim. I am using a th400 that came with the engine. My first problem I would like to solve is the firewall issue, it is a little too close for the engine to mount where it should, and I am wondering if it would be easier to cut the firewall and make a new firewall/tranny tunnel that is farther from the engine, or if it would be easier to modify the frame and move the frome mount pads farther foward.

Also, any additional advice or suggestions are welcome! I am fairly new to hotrodding and I am open to ideas.

Oh! and I should probably say, this is a race only truck and I am not interested in daily driving! I am racing in 1/4 mile and I am always interested in going faster.

Hi,
I think you should cut the firewall, I
don't think I would be in a hurry to
move the engine forward.

Go to v8s10.org, and we can guide you through it. A few guys have done it and it's pretty straight-forward. Headers aren't going to be cheap though. Check out the link (I'm chevykid over there). Good luck with your blazer, I've done 3 v8 s10's and boy are they fun!
