what kind of porting and polishing are you getting for $350?

 

Especially the kind that makes 380rwhp with a 224/230 cam and Mac shorties They'll put every other head ported out of business. I don't see valves in your list so I'm assuming thats with stock valves.

 

Can I make a suggestion? Get new cam and crank gears to go with the new timing chain. The gears will have worn to the old stretched chain and will not perfectly mate with the new one. I have always replaced the timing chain and gears as a set.

 

That was an approximation a long time ago, I know it wont be very close to that, maybe 350 or 360, it is a guy that builds race engines, hes doing everything you can do without increasing valve size.

Didnt know I should have replaced the gears shoebox, hopefully they are alright, cuz I really dont want to tear into there again.

 

It'll live. Just one of those things I prefer to do. Didn't realize you were done already.

 

What you guys think my best guess is for power, not so much hp high end, not what im looking for, but max torque, I know this cam is a really good low end torque cam. If my starting point is 280hp/311tq at the wheels, that was with nothing in the list above. Approximate numbers, Im guessing around 350 or 360 for both hp and tq
