2 much cam. were ur tires et drag or et streets? also the ms3 cam is made to work best in autos. I also dont think u dont have enough mods to support the cam to make it work best.

deff got those stock heads trying to work with that MS3...perrty big cam for stock heads...... I'd say it's choking out from being slightly over cam'd...my 95 did it a lil bit since I stuck a big cam in with stock heads....but it was a nitrous car and the Nitrous offset it in my setup...

tires were et drags ...im gonna be putting ported ls6 heads and fast 90 combo next week and then prob full suspension in about 2 months

more air should help up problem. also ur gona need the suspention like u said. I've been to that track twice and the first time i was getting back in the grove of racing and the second could not hook. i'd also suggest a 255lph fuel pump and possibly bigger injectors. then retune and make sure they pull timing for ur nitrous.

also try a set of DRs..might of had too much tire and not enough hp

well timing is retarded for nitrous but i went ahead and ordered the timing knobb the way mando has on his camaro so once thats intalled im going to get a full tune on motor and a full tune on nitrous and i can retard the timing manually from inside

Deerhunter-Z28

exactly what I was going to say, but I bet you just needed to add some air to the tires and you would have had better results.

Try a set of drag radials. Drop the hammer at 5k and go up from there until the bog goes away. Thats a big cam but plenty of cam only 6 spd cars have ran good numbers with it.

I thought those ***** and retard boxes worked on LT's. i know if they dont pull timing for nitrous after a while your engine will start smoking. but as far as ur bog issue. ported heads a larger intake and maybe 1 7/8 primaries on ur headers. the more mods u can get to make ur cam work for you the better.

well i was running the tires at 12psi what should i go up to ??? Maybe 14-16 psi??

Deerhunter-Z28

I would probably start at like 17-18 and go down from there depending on the track. That cam really needs a 4.10 or 4.30, but that 3.73 will work but you honestly might have to drop that sucker off the rev limiter, like 6500 or so to get it to hook. I would see if you could hook on 16-18 psi or as high as possible and start dumping it around 5500 and go up 500rpm every launch if it keeps bogging. That sucker will hook believe me, you just have to play with the tire pressure and launch rpm.

You just need to drop the clutch a little slower, you dont have quite enough power to just dump and go. I dont see what raising tire pressure is gonna do unless your trying to get it to spin just a little to get it out of the hole, but I dont think thats going to be enough. And if you switch to drag radials they will most likely hook just like your slicks (at least mine did) or let loose completely. It's a lot harder to control spin with a dr than a slick, especially in a 6 speed.

Oh and like deerhunter said, you REALLY need to get some gears better suited for your cam.

heads and intake before you figure out your issue isn't the best use of money. I personally like the idea of suspension first. You see immediate benefit from this AND it supports future upgrades. Adding power when it's not hooking right just spins the wheels/tires more. . .

thanx i wil try that ...and about the gears if i go 410's do u think i wil run out of gear when running on the bottle ???????????

Deerhunter-Z28

Probably, if you do you just need to go to a taller tire.

Deerhunter-Z28

That might help if he can slip the clutch, depends how good of a driver he is. I used to get my cam only car to hook w/ stock 3.42's but I was literally dumping the clutch at about 6500-6600.

Deerhunter-Z28

Well said.

Usually I would agree with suspension coming first, but in his case he's not having traction issues. He just needs to practice his launches. If I try to just dump the clutch my car does exactly the same thing, you need to feather it a little to avoid bogging.
