No one has an opinion?

i think nobody wants to give an opinion because the next guy will of course say, "no, thats not what you want." LMAO!

I didnt see a mention of F.I. or carb. IS this going to be a dedicated drag race or pro-street type build? How high do you want to push the RPM's?

I'm thinking your looking at a nitrous cam with lots of duration and lift, going by the information provided and the brake. probably somewhere around a 290 on up duration?

OK,...the ice has been broken.

Solid roller?

I'd go something like 256/262. .650/.650 110 lsa. Somewhere around there

Hydraulic roller i'd go 242/248 .600" 110 lsa or similar

thanks both for your reply's yes this will be a 99% track raced drag car from now on beside the occasional once or twice a year drive across town for a show it will be carb not fi im still deciding if im gonna run alcohol or race gas race gas is allot easier to get in my area then alcohol with the heads and intake im using i would say i would need to pull around 7.5 to 8 thousand rpm to use there power im not sure if i should use sold roller or hydrolic roller i whould think solid with that high of rpm what do you think this will be my first roller build always used flat tappit before this but tired of loosing on the big end

You are better off solid. But you can get a hydraulic that high but you need short travel morel lifters, big pushrod, shaft rocker for precise geometry and pretty stout springs with titanium retainer. Cam lobe has to be relatively milder to for top end stability

ok so it definitely sounds like ill be going solid roller just for ease of mind then

Right... what bracket, dial-in, goal, whatever... wouldn't hurt to tell us how long a track you plan to run as well.

Those pesky details.

estesformula87

ill be running 1/4 i hope to at least be in the tens with the bottle my machine shop thinks i can get med to low 9 on bottle but u know you can hope in one hand lol

You'll need a bigger shot on the bottle to go mid low 9 but motor should do 10's at that weight if you have some compression

estesformula87

yeah eventually im gonna add two more stages of nitrous but i think im gonna need a better crank before i start throwing that at it
