I need a good cheap motor so I am going to buy a GM
crate motor long blockwith 194 heads $1,345. 8.5-1
compression 74 cc heads 220 HP , I have new Vortec heads 64 cc
and a Vortec intake GM seed I will have 9.6-1 compression
using my Vortec heads but will lose my warranty which is ok with me .
Is this a good idea and how much HP increase should I expect ?
The motor will be for street use in my 1977 Chevy 1/2 ton short wide
2 wheel drive lowered
