X4 I have a stock stroke 363 with W2 heads 11 1/2 to 1 comp made 549 hp and 450 torque, my present motor : R3 Block, Indy 360-1 heads 4 inch stroke comes to a 408 91/2 to 1 comp . made 539 hp and 502 torque because of the increased torque I am able to run a 4.10 gear my 60 fts stayed the same vs 4.88s I ran with the 363. Didn`t need all the gear because of the torque increase.

Why do you guys insist that everyone build a Stroker engine. A stock crank 360 is a great platform that can and will run great with the right combo.

At the risk of being a jerk; “1970 Duster Edelbrock headed 408 6.143@110.89 mph 9.73@135.05 mph shifting at 6700 RPM 422 Indy headed small block 6.001@113.27mph 9.44@138.23” Also he is concerned about his cars weight and missing out on low end torque. Can you recommend a good dual plane for his W2 heads that are readily available? Otherwise, I suggest a Holley Streey Dominator since the intake runners are slightly more narrow than the MP-M1.

You have to explain "low end" first. Stroke doesn't make power. That's why you have a transmission and rear axle. The actual RPM of a 4 inch stroke compared to a 3.58 stroke is about 400 RPM. Maybe. So we are talking about a shift speed of 7100. Not earth shattering by 1999 standards.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

Just for an RPM example my son was having a shift issue last Sunday at Keystone with his air shifter so he lowered his shift RPM from 6600 rpm to 6400 rpm on his stock stock 360, at 3200 pounds, 727 transmission, and 4.10 gears and in 90 degree plus heat it slowed from a 6.62 to a 6.64

From a purely pragmatic standpoint......
A SCAT 9000 series 4” crank is less than $400. For that price I get an additional 40 cubes, a crank that is easily internally balanced, which gets me away from needing a weighted flexplate/converter and 360 specific damper. As a bonus, I don’t have to pay $150-200 to get a stock crank cleaned, magged, and ground.
IMO, it’s a no brainer.

IMO, it’s a no brainer. That is my thinking. A bonus! From 360 cubes to just over 400. That will add torque quite well. Proper camshaft selection is the next step.
