200+whp stock manifold/TB m20b25 (no ITB, no stroker)

Just got a Euro Shark 635 that made a deposit today to do a high-strung NA build. It's 10.25:1 stock, we are upping the valve diameter, flowing the head, using a 290 cam and a Weber DOCE-3 manifold, DOCE-style ITB's. Throttle diameter TBD, but plan is to do something similar to this m20, just + displacement, and a lot more car to pull around.

That sounds right up my alley! Let me know how that car does- I'm sure it'll run great. Rama just finished up the M30 ITBs he's been working on BTW, I don't know if you saw that or not. Doesn't apply to the shark though if you're carbin' out with some triple 40s or something.

Q) Whats it got for a bottom end?
A) 14:1... errr its stock hahah

This is just proof that M20s want more compression and the stroke is more for the torque side, right?

That thing sounds awesome! Have you done much with M30 stuff? I wonder how 3.5L would respond to more compression, nice head work and a matching cam.......

SCCA EP class compliant. Rules state less than .5" lift, 85mm bore max, 75mm crank, stock valve diameter. This is a 12:1 m20b25 with a ForcedFirebird head, Schrick 288 cam. Dyno'd off-site on a Mustang Dyno. We use a Dynojet for normal operations. Logistics say, it's a long drive from New England to FL....
