Which cams should I go with?

[Winters98GT]

yeah - i've always been weary of stage 2 cams and a PI swap cuz of my flat top pistons and the clearance decreased - but it's good to hear there isn't any problems there. I already have beehive springs on the head, but i just dont think my heads flow enough or i want to rev high enough to feel that difference. Although i can get used stage II's for about $150 less than buying new stage I's, i don't know if it's worth it

the flat top pistons in the 98 will not decrease ptv clearance with PI heads. Ive read many threads on this, mainly posted by greenbird on the mondulardepot and the gererally concesus was that it was not true. Ill see if I can find the threads tommorrow.

So if I don't go with cams should I still put new valvesprings on the heads?

No. The stock springs will handle whatever the stock cam can give them. The 262 wouldn't require new springs. The 270 should have them though. But, you talked about just going with a supercharger and forgetting cams, etc. I'm not sure you would be "happy" because, while the s/c is great for making some power, you would need to forge your lower end to handle it (I found that out the hard way), and then your weak link would be the heads and cams. Doesn't do a lot of good to have a huffer trying to shove air through small holes which aren't open very long or very high. It's great for boost though! Work on making a strong short block and work on the heads and cams before you do power adders. Just my opinion. Good luck. (Forget aftermarker valve covers. Cost too much and contribute nothing.)

Correct. The dish size doesn't mean anything....the valves hit the crown area of the piston.

aww yeah, that actually makes sence
