not too much. its got 1971 heads, so no exhaust bumps. Had them ported a bit more anyway. Have the comp K kit, weiand intake, edelbrock 1406. Stock dizzy. Msd 6A. ARP bolts. High flow water pump. Hedman headers. I wish i had bumped up the comp ratio when I had it done.
Power wise, I think its a bit weak off the line, but tows nicely at highway speeds and on hills. I'm running 3.73 gear ratio with 31" tires.
Fuel...ummm..it sucks, literally. I think I get less than 10 with my boat behind it.
