It's all in the heads....depending on the port job you could be running mid to low tens on juice to 11 teens on it at the track. I wouldn't be surprised to see 420rwhp out of this...although a slightly more aggressive cam would be better imho since the 306 is smallish for a max effort motor and also isn't ideal for spray with the 112lsa...but it should still be fine. Save up for a rear end...

also what type of tranny are you running? because stall size, tire size, suspension setup etc etc will determine a lot of what times you are going to cut. Also vehicle weight and who is doing the tuning?
Dont even attempt it on the ten bolt or youll be disappointed. also for the spray and the stroker you should get a cam to accent it. Ie:236/245 114 lsa with a little more lift on the exhaust side like .569/.580 and dont you worry bout where I got those specs from 
but something like that would help you especially if those heads flow good. remember a big cam in a big motor isnt so BIG anymore.
I think youll put down about 420 also and a real good amount of torque

i'm running a 6speed.
25thAnnivTransAm- you think i will even go the 60ft?? on slicks more like 6ft!!
i was going to do a different cam but this one was free and brand new- after some runs and see what kind of power i'm making i will start looking for a different set up!
what stage clutch should i look into?? or what kind of clutch? what about a twin disc!?

Verdad Gallardo DO NOT BUY A SPEC! Just buy a street twin and be done with it. I went through 2 stage 3s the damn spring popped out of the disk after 2000 miles and I broke it in just the way they said to.. It never even saw a dump above 3500...I have a street twin and many high hp cars have been running with no probs

With a 6 speed and that kind of power on any kind of a sticky tire (even a DR) your stock rearend is gonna go KABOOM! And since the motor is out and ur building it y not just spend another 300 on the cam that's gonna net u so much more (power and fun

sweet...yeah a cam swap would be cake after all this labor. In a 6 speed car the rear end is going to be taking a beating with any aggressive driving...i would seriously look into some suspension to eliminate wheel hop and stuff like that so you dont go breaking **** on street tires. DONT HOOK...which I'm sure you know that already. For a clutch...I had a centerforce dual friction for about 3 yrs and 30K miles with lots of aggressive driving...clutch dumps etc.... There are many horror stories about the spec stage 3....but I've only heard good things about the 3i and hybrid clutch. I've also heard horror stories about Mcleod Twins...I mean face it **** can happen with either clutch obviously, but spec has had more negative feedback, prolly cuz more people buy them because you could buy about 3 or 4 for the price of one mcleod twin...just a thought. My vote...is for the centerforce.
But the reason why a mcleod costs so much is because it comes with a master which is billet not plastic like the stocker, a new flywheel, pressure plate and two clutch disks...The only people that have problems with the mcleods are the ones who didnt put it back together exactly the way it came with the shims lined up right. Plus tbyrne has group purchases all the time on them and I paid 895 to my door for it. A spec 3 is 500 bucks and waaaaaaayy more hard to drive than a mcleod although its still not bad

Definetly get a new rear in there before you go playing.
And dont get a SPEC clutch, they're garbage. The centerforce ones are alright in my experience.
