are his heads ported? If his heads arent ported id say the numbers are correct, plus not many 400's make 509 ft lbs, thats what the increased stroke of his engine gained him if everythng else is equal with a 400 with stock heads . Now if his heads are ported Id say he has a problem somewhere unless his cam is very small

The heads are 670. I don't have the paper work on all the items for it intel I pick up the motor. This is for a daily driver car I didn't want a large cam in it.The machine shop was to port the heads and intake HOW much was done I don't know yet. They did say the dyno was on the low side. Accoriding to the numbers on the block with the old factory heads it only produced 325 hp.

There is his important info!
KSGTO has 500+ ft lbs just about anywhere above idle! That is street fun!

When I putter around on the streets I could care less about big HP numbers, its big torque I want.

where does a cammed up 400 have to spin to hit 500lbs torque?

One can be as fun as the other especially with a 4sp, I guess it depends on each persons style.

670 heads with a 461? Lets hope you used some dished pistons!
BTW, the original factory hp number for your block means absolutely nothing.

So let me get this straight. Pay big bucks to have a stroker engine built, and use a 204/214 cam with 2bbl heads with small valves, probably using a 2bbl carb, but try and make more torque so you can fry the street tires even more on the street, but not concerned with more power??


Lost 1, this is Lost 3, are you lost too, over?

This hit the nail on the head...
