I have a 1986 gmc subrban with a 350 small block. I want more power... its a big truck with a weak motor. I was going to pull it anyway to rebuild it cause it leaks alot of oil and its tierd... but while its out id like to add a little snort while im at it.. as of right now its got a edlbrock 650 cfm carb and long tube headers.. thats bout it for aftermarket parts. I have a highrise intake i wanted to put on it that was given to me cause why not. Anything helps im looking for ideas cause in time it will have 32 or 35s on it so i want somthing that can get out of its own way.
