ive tried calling vortech and asking them what camshaft they'd recommend but they seem to always be super busy.
i have an idea of what i want but heres my setup:

afr 185 heads, trickflow trackhead intake, 70mm tb, mac equal length shorties, magnaflow exhaust, srp pistons, manley rods, vortech s-trim @8psi right now (plan on boosting to 14).

idk, thats the basic rundown right now. just seeing what you guys were running. im sure theres someone on here with a similar setup. its a new setup so i still have my old nitrous cam in there (112 lsa, 510-522 lift, lots of duration)
i know the cam i have in right now is seriously hurting me.

Stock block is fine for now shouldnt be over 450 rwhp with a decent cam. Off the shelf a F303 is a pretty good boost cam, had good luck with mine and it has made good power. Custom is generally the way to go though.

I reckonsome sort of cam where there isn't a lot of valve overlap, and the ramp rates aren't real aggressive. and while most reccomend a split duration cam for a small block ford, that's usually for Ford production heads, where as most people know the exhaust flow is terrible, taking the air in, isn't a problem, its getting the air out. However you're running top of the line AFR's so you could definitely run a single pattern, and may actually benefit more than you would with a split duration. I've heard but don't know with personal experience that the F303 is a great s/c cam, and with it's profile, it would compliment your set up quite nicely.

I would also reccomend checking into an Afm cam. They've got some great quality stuff for all applications.

Turbo isn't going to stress the front cap like a supercharger will . . .

I have seen stock blocks last 100rwhp longer with a turbo vs a blower.

When I talked to Comp, we ended up coming to the conclusion that a comp 284hr would be a good match for me. I don't have the motor done, but here's the combination. 302 shortblock, twisted wedge heads, ported gt40 lower, tubular upper, 284 hr, s trim 13 lbs or so of boost.

Ok and my car had a supercharger before? 450 should be fine for a while as long as your not reving it past 6k or so.

I am saying I ran a supercharger before the turbo and had no problems. Its mainly the rpm's that break stock blocks. Will it eventually break at 450? possibly but it should last long enough until he wants more power.
