W2 408 build

Nice power out of that combo. Is that corrected?

Not to hijack but... my iron headed 416 is very similar but you made almost 45 more hp than me! Huh.

My heads flow almost exactly the same as yours, my cam is a solid FT, 251/259 @ .050" with a 1.6 rocker, around 10.3:1 CR with a zero deck Diamond dish piston. I used Total Seal rings. I ran a 2.02 valve though, an 850 carb and a gasket matched Strip Dominator intake. Same exact rods.

I used a HV oil pump, my understanding is that those oil pumps can rob a little hp but it's a street engine, I guess I was just stuck on the idea I needed an HV.

Hard to believe I left 45 hp on the table with those parts. I know a Victor could be 10-15 but the rest does not add up. Oh well, nice job should be fun. Would like to hear results when you get it down the track.

Hello rmchrgr,

Dyno sheets all say standard for correction factor. Sounds like you have a very nice combination yourself. The only comment I can really make with substance behind the possible reasons for difference in H.P. are the carb, and attention to detail. I do NOT mean your engine was not built with attention to detail, only that this engine was built by a gentleman who builds stock eliminator and Superstock engines and has very successful race cars. Much of the power from engines like he builds is from exact tolerances and such. These guys need to make huge power using engine building techniques I don't claim to know anything about. While engine was on his dyno he put on a proven Quick Fuel Q-850 as he felt the 950 might be to large. Much to both of our surprise the hp was down by 20 even with jetting changes.
