ok i was debating on even asking this but here it goes, dont jump down my throat please. lol. ok can you run pump gas with a 10.5:1 comp ratio with a camshaft lift at around .680 ?? im building a motor and wanted to put a monster together, just wanted to go as big as i can on pump gas. take it easy on me...lol

Why do you need to run a cam that big?

why not?..lol its going to be a strictly for fun car, and i want it to be the meanest small block around.

The cam should be the LAST thing you buy and it should be spec'd out based on your combination of parts.

10.5:1 is fine with pump gas and aluminum heads. How do you know what your cam specs need to be? I think you are going to be very disapointed.

If you don't know anything about camshafts and valvetrains and you pick your own cam specs, you aren't going to have anywhere near the meanest small block around.

ok heres the deal, I am building a 347 stroker with the new boss block and afr 205 cc heads. The camshaft is out of my Grandfathers nhra superstock car. its a solid rollor peice. i dont know exact lift (he has the cam card somewhere). but I'm also using the jesel valve train and all. and being that he runs a similiar combonation that it will work ok together, My heads will be even better so i cant go wrong. i realize its not the exact cam for my combo, but it will get me by. it should make ok power though.

10.5:1 is fine for pump gas... If your stuck on that cam, I would be interested in notched pistons and a great valve train to support the lift

[Mlx50man]

ya i have the shaft rockers from jesel.

lolz, you need to start readin pal. i love you said you want the meanest SB around and then you say it " its not the exact cam for my combo...it should make ok power" was your grandfathers superstock a 347?

Yes, you can go way wrong. A cam for a SS car is not going to be the same as a cam for a street car. SS has a bunch more than 10.5:1 compression for starters. Secondly their camshafts are overly huge to make up for a poor factory head. Thirdly, the cam design is based on much more than the cylinder head and cubic inch. Its your stuff, do what you want but that cam won't be anywhere near correct and performance is going to be weak.

Why AFR heads? Just curious....

With AFR heads and a Super Stock grind, I'll agree with you.

[dblzroracin]

If you are spending that much $$$ on a new Dart block, alum heads, Jesel valve train & stroker kit, then why would you get cheap on something as important as the cam to go with a used cam that was designed for a different motor combo? You can get the best custom grind for your combo cheaper than any of the above mentioned parts?

AFR's because i can get a deal on them. and as for the ss compression ratio. it has to be stock specks. so you might want to research something like that before just saying it. and i want the meanest sounding sb. it just something for cruising and shows right now. when i want all the power i'll have a cam ground. I just know how this thing sounds and i want that sound. but i knew when i asked this question that you guys would go off on rabbit trails. but my main question was would it run on pump gas>????

Ok, nevermind......its not my scrap. Put that cam in with those AFR heads and drive it. It will run on pump gas. It will run poorly but I guess that really doesn't matter.

I've got $1000 that says 93Mustank's used parts 306 will run circles around it.

look man, it probably will, because the car isnt built for racing yet either, its just a straight body show/street car, but you never know, the motor might surprise you. as for his 306 i have another car that would take car of that.

[Mlx50man]

I dont know why you guys always have to be downing people on here. is it so hard to answer there question? its different if they ask you if it will perform well. but i mean common. i read on hear alot and some people just want to use stuff whether it works or not. so just try and chill.

It doesn't matter if the car is build for racing or autocrossing or whatever. 93Mustank's car is a daily driver. The point is that engine is going to be a turd. While it might feel great to you because you are used to a stock 5 liter, other 302s and 347s with well matched set ups will be leaving it in the dust. You are taking short cuts and I'm trying to help. Being a street car should make it that much more important to you to run the correct cam.

No it won't suprise me. Its a bunch of mismatched parts and subpar heads.

No reason to throw other cars in the mix. We could play that game all day. That wasn't the point. The point is you are spending all this time and money on a 347 that is going to be a turd. Then you contradict yourself saying things like "wanted to put a monster together" and "i want it to be the meanest small block around" and then "just something for cruising and shows right now when i want all the power i'll have a cam ground" and "its just a straight body show/street car". You are making excuses for a combination that isn't going to work. If you don't want any power than why are you building a 347 and getting shaft rockers, etc? That is a foolish waste of money for someone that just wants a show/street car that sounds nasty. I can make a stock 5 liter sound nasty with a mild cam and some exhaust work.

One other suggestion, if you are in fact getting a Dart block then I would go with the 4.125 bore instead of the conventional 4.00 bore.
