Ive got SRP .30 over pistions in my short block, going to be using Twisted wedge heads and a ported and polished upper and lower cobra intake (flows like a track heat). DO you think a N-91 cam would work good with it, got a buddy that has one. Its the 6900rpm one. Heres the specs on it. 240 @.050 intake and 248 @ .050 .576 .576 110 THink thats over kill for my combo? I want to make it run good on motor and also run a 125-200 shot on it. Anybody runing this cam right now? The car wont be a daily driver but it will see alot of street action though, wondering how the drivablity would be with it.

I'd would say that's too big for what you're wanting to do. I wouldn't use it.

I would call Rick Anderson to find out what he would recommend.

Idle quality will be pretty low, at a typical rpm of 7-800 rpm. You may need to put the idel up in the 1000+ range.

I'm sure that cam's powerband is in the 7,000 rpm range. Just a guess, but I'm sure it can be found around on the internet.

This is if it clears those pistons

The N-91 is NOT the cam for you.

Rick Anderson recommends that N-91 cam for high compression, 7,300 rpm, with 4.88 gears...lol on a 302.

The trick flow stage 1 is a good cam for what you are doing and matches well with the 302 induction needs for a good budget. It is very popular actually

Yeah the N-61 would make more power than the trickflow stage 1 cam

The N-61 is designed for aftermarket or notched stock pistons. A shift point around 6,200-6,500 and with the powerband between: 2,500 and 6,500 RPM. Get some good valve springs to match, in which www.andersonfordmotorsport.com can help you with.

Click to expand...

Wheres the rest of the 80hp you should be making with that combo?

Most combo's using those parts I see do 375-400hp.

I wouldn't recommend the tfs stg 1 either. I used it for a few years and it was nothing special. The N-61 Rick recommended will work well. You'll need at least 4.10 gears. I like the N-61, we use it in my boys car.

I ran the N-61 on an old 302 combo with a 3:73 gear, it ran very well but more gear would have been a huge help at the track since I was only trapping around 5200rpm. My car made 340RWHP on 7cyl's..lol Never went back for a clean pull with all 8. My best pass was a 11.7x @ 116.8mph, 1.601 60ft I believe... I made power up into the 6500-6600 range, it had a nice curve but the power dropped off pretty quick once it peaked, same goes for the N-71.

If you do not want to notch the pistons (although most aftermarket pistons should allow the clearance you need) will the N-41 is a good cam, otherwise a true custom cam from Flowtech Induction would be a good choice, and money well spent.
