Well the time has come for me to upgrade to a dart based 363 build. Woody built me a nice stock block 347 that has served me well over the years, but feel a bit nervous about the limiting factor of the stock block, plus I can gain some power going a 363, and higher RPM's.

Im going to use current top end configuration, which is TFS BoxR, TFS 190 11R, and Accufab 90mm TB. Its a roller hyd lifter block.

My first question will be what cam specs would you recommend, and the second will be about running vac pumps and piston air gaps.

So the engine is used for circuit racing, and will limit it to 7000rpm. I want nice torque in the upper regions of the rpm band say 4000 - 7000. I don't want a torque monster so to save the trans a bit. I am hoping for a an honest 550+hp

car weighs 1600kg, and runs a T56, and 3.45 diff.

Appreciate any experiences

What I meant by air gaps I meant gas porting. Can I ask what peeps think about this. I intend to run a vacuum pump, and Woody uses LF 1.2mm rings for his Wiseco Pistons.

Thanks

I have a cam card for a cam Roush spec'd for my flat top AFR 205 headed 363 but it is carbuerated and solid roller.

Thanks Bam, but probably not the same.

I had a look at CompCams and their XFI248HR-14, which is 248/258. Also the Andersen Cam N-114 but that might be too big.

Also looking at the N-91 and N-111 cam profiles.

I'll end up going Woody's custom grind, but its good to get some ideas from OTS grinds.
