Default whats the estimated HP

306 block, keith black flat top pistons, I beams, windsor jr heads, gt40 upper and lower, crane cam/crank, pushrods, springs, full exhaust and cai with 24# injectors.

This is what the car I am buying has. To me it looks like just with the engine its worth the 1900 I am paying for it. Needs a new trans cause the old T-5 blew a gear as usual and the interior needs work. less then 10k on the built motor.

Whats the estimated HP? I dont know any of the specs further then what I gave. I am thinking the CR is around 9.5-1 and HP seems it should be around 330-350 rwhp

about 300 is a good guess, depends on some variables though. as low as 240, id say 300 max

you say "gt40"

does that mean...."real" gt40, "explorer" or "cobra"

theres a big diff in the 3

Never heard of a Crane crank.
Could you tell me about this?
It could make anywhere from 150HP-330HP easily..........

They shouldn't be that bad, there's always better out there, it just depends on how well the setup works together and the state of its tune.
