3100/3400 cam question

[BumpNgrind777]

What I am wondering if these crane cams will work with my motor. Its a 3100 with 3400 top end, port and polished gasket matching, 2.5in custom downpipe stock manifolds, and a custom tune and willing to retune after cam. This is also in a short track race car for race usage only.

Basically no... Those cams are flat tappet camshafts and the 3x00 is a roller cam. Only place to order those cams is Wot-tech.com

That's what I thought but wanted to make sure. So which cam from wot tech do you think would be good for me? Most tracks are shorter. The car is ran in 1st gear shifts to 2nd here and there never sees 3rd so mainly I want that short distance quickness. So for what's been done is 3400 top end ported to match gaskets and polished, 3400 tb, 2.5 downpipe, custom tune ran on a wheel dyno, and a different torque converter. My plans this year are a cam stiffer springs in the heads and headers (hoping to make). My thoughts were the torque cam they offer. any input on cams, anything else I can do to bring more life to this motor without?
