Will my Trick Flow 170cc intake runner 61cc chamber work well with 408ci?

[Pokageek]

I never run my car down a track and enjoy light to light driving. These have to be better than a stock 351 head for example. Any power estimations with this head? On nitrous with a 100HP shot (with real dumb timing) I made 350rwhp with my 306 on the dyno and 376 rwtq (if i remembe correctly) with these heads.

I want to hit over 400rwhp - no question. Will I miss my goal?

A guy over on corral runs 10.30's @ 128ish using unported twisted wedges on a n/a 408. They have a good v/j but no porting or anything.

400rwhp shouldn't be a problem at all. You'll need to mill them down to get the compression up and obviously new springs.

Thanks. Why new springs though? They only have like 3 k miles on them. Sorry if dumb question. also what is V/J?..oh , valve job..Don't they come that way though?

you need new springs if you bought them assembled from trick flow, because i belive they can only handle .500 lift and you would need more than that. v/j is valve job

Ok. Thanks!

302 parts will get you 302 power. Send em off to get some work done.
