408 build and results.

If he had the KB 191’s, that would be different. 11.20 cc dome.

My bad here. I was thinking of a stock 3.58 stroke with the KB 191’s. It would look like;

And what fuel to use here?!?! LMAO!!!

carry on friends….. back to stroker talk….

There is always alcohol, buy it by the drum. LOL

What size are the headers the motor was tested with?

1 3/4"

I used that same cam in my 500 stroker. It made right around 100 ft/lbs and 100 HP more, with the same flat torque curve. The combination was not maxed out by any means, but it was a blast to drive on the street.

What are the details of your combo?

You made 584 hp and 616 ft/lbs from yours with that cam?

I made 550 hp and 610 ft/lbs of torque on the dyno with pocket ported 452 heads. I later switched to Edelbrock heads and picked up about 2.5 tenths, so I am guessing at least an extra 25 hp and who knows how much more torque. It had a 4.15 Eagle crank, dished Icon pistons, about 9.5 compression, Holley Street Dominator, Holley 750 DP and 1 3/4 headers. I know everything is too small according to the experts but it was a torque monster.

I missed where you wrote "...500 stroker..."

500" BB stroker netted 100 more HP. That's 92 more CID at 1.1 HP/CID.

And the OP was a 408" SB stroker at 484 HP. That's 1.186 HP/CID.

I actually expected more out of the Trick Flow heads, even taking into account the cam and intake. I'd have guessed a 500h.p plus engine all day.

The heads are not holding it back from 500 hp. Brian at IMM built my 408 with out of the box trick flows and air gap manifold and got 506 hp and 506 tq on his dyno. Hydraulic roller cam of his specs but tame enough to run PB and A/C. Willingly gave up some hp for that.

Looks good

Pretty short duration cam, dual plane intake....... that’s going to kill off a little top end.

But I bet it will pull like a steam engine from 2000rpm.
