How Fast with a Flat Tappet Cam

[KEVINS]

I would suspect that most are running roller cams but I'm curious if anyone is running low 10's these days with a flat tappet cam and how large does it have to be to run this fast?

Depends on the rest of your combo, but i just went 10.16 a week ago with crappy 60ft (still working on that) and limited boost
212 flat tappet
Baseline kit
I plan on running in the 9s shortly.

I have been 1.44 with your kit but only once so far, track prep sucks where i run.

So... how fast you gonna try to go? I may have a turnkey combo for sale

I have seen the stock cam go 10.3's.

I'm just hoping to run 10's which the stock cam will do fine but I was curious how fast people have gone with a flat tappet. It seems that most switch directly to a roller these days and I can't say that I blame them.
I've been getting the bug for a 9 sec street car and if I was going to actually do this I'd get a turbo'd stang..

Why would you even contemplate that??? You're already making STUPID POWER with 35 psi of Anti-Vacuume with your GN right?

lol.. Yea, but I've been wanting a 9 sec street car lately. Besides I could use it for a test bed for future part development.

You have been into stangs for a long time now. I just googled something about suspension this morning and you were in one of the posts that was from 2001 on some Ford site.

wow..although I can't see why not

Yea, that's about the start of the business but I've always dabbled in them for the last 25 years or so. The last one I owned was about 25 years ago and with everything I have developed for them I've never owned a car to use for mockup.

It was on 28" tires, it was laying over big time up top. With a taller tire it would have gone faster.

I can see that with the lighter T's and the right build. Too bad there aren't more out there doing it.

I'd change to a lower gear instead of a taller tire to keep the weight distribution more even for really hard launches.
