beefing up the stock 318 engine CHEAP mods

So far on my gear change in my 8 1/4 for my M body, I bought a decent set of used 3:55 gears. $120. Cant imagine spending another $280 to install them myself...

I had no idea the factory head gaskets were .028 thick. Mr gasket does sell thinner ones.

Agreed on the headers. I spent $50 on my used set,which havent even been run,just trial fitted and bashed a bit. They look just like hedmans. You will need header bolts as well as gaskets,again cheap.

A cast iron intake should be cheaper than any aluminum intake and they are actually a very good piece. it's unlikely you'll encounter cracks or stripped holes. If it's spread bore,it'll bolt right on. Dont pay more than $25.

I still thnik gears would give you the most bang for buck in the acceleration department,IF you can get a good used set for cheap.
