Cam with stock heads....
Cam with stock heads.... I would like to know what is the best cam for stock heads...I just don't have the money for heads right now.
I was thinking about the LT4 Hotcam kit, or does Comp make a good grind that would work well on stock heads, with LTs. THanks

xe 233/239... with stock heads, stock intake, full weight hardtop with 100 shot, lt's, tb, k&N, msd and M6 with a stock 10 bolt... went 11.47 at 124 on 3.42's and nittos
the car has never been on a dyno and sat door to door to a 500whp trans am 100shot for 100shot.... so you can say its around 400 on motor to the wheels... possibly a lil more considering the t/a the car ran had weight takin out

Why not just port your heads yourself??? It ain't gonna hurt anything, and ain't hard. Just takes time and patience. Comp Cam 305 or 306 would be great choices. I think the 847 would be a little much unless get a 52 or 58mm TB, bigger injectors, etc. You might be alright though.

The F13 is sick for stock heads and beter than jsut peak #'s the power under the curve is insane. CHeck it out at FUTRAL. the specs are 230/232 585/595, I got mine on a 112 +4 to try to salvage soem low end torque.
Havent been on teh dyno yet but these cams have made 400 rwhp on stock heads and are very stretable. Plus you have an M6 so no worries there.
cheers
Damn! just realized you are an LT1. My bad. just ignore my rambling.

The CC306 and 847 would both be excellent of the shelf choices. Might as well only do a cam swap once right? The springs need to be changed with almost any cam and a set of adjustable roller rockers arent a bad idea either. As far as a bigger t/b you can port your own to a 52mm and port the t/b to match it. Not really a big deal, and as for the fuel injectors...the stock ones are fine for that application...if you spray down the road then injectors should be replaced. We swapped in a cc306 in my buddies 97 lt1 vert....(30thz28) and it ran like a raped ape. If your an auto...you will want a stall and some gears....or if your a m6 get some gears....tuning on an auto is a must...but it will run decent w/o but for max hp get it tuned. A cheap mail order tune will do wonders pcmforless is highly regarded on this board. Good luck.

the 847 and the 306 are almost identical. I have never before heard somebody suggest one and say not to go with the other. There are minor differences, but saying "Go with the 306, but the 847 is too rough" doesn't make any sense. The 847 is a bit more aggressive, but not by much.
Don't touch the heads if you don't know how to port. Don't even try it if you don't know what you're doing.

I run a 233/239 cam with heads flowing 280cfm @ 0.6 . . . had it on a Mustang Dyno not too long ago and hit ~380rwhp. With a electric water pump, some underdrives, and 1.7 rockers, I might be able to hit 400rwhp. Granted, if I put the car on a dyno-jet instead of a Mustang dyno, it probably already passed 400rwhp, but not by much. Unported factory LT1 heads flow ~215cfm on a good day. The less the heads can flow, the bigger the cam you need to make the same power - and the higher the rpm. Given that the LT1 computer is limited to 7200rpm, I would be impressed with any stock LT1 headed car hitting 400rwhp without a blower or NOS. If you happen to own one of the 100 or so factory LT4 powered Camaros or one of the Grand Sport Vettes, it MAY be possible to hit 400rwhp cam only. Even then, it would have to be a significantly bigger cam than what I'm running (possibly solid roller) and you would need all the boltons money can buy. Not saying it isn't possible, just not very likely.
