ive got a 91z 350 with a stealth ram. Ive got a chance to buy a cam for cheap 236/242 at .050 .520 .540 and I was thinking dart iron eagles or used afr 195's. I'll use a built 700r4 and a 3500 converter. 3:73 gear.
Do u guys think that the cam is too big
I know a cc224/230 or a cc306 would work good but im on a real tight budget and the cam is a hell of a deal. This is not a daily driver and I want it to thump hard. Oh yea ive got a 150 shot

I dynoed out at 402rwhp and 615rwtq with a stock long block, bolt ons,HSR and nitrous, stock tune

 

There's no such thing as too much cam, just not enough motor!

It is a little on the big side, particularly for an HSR, which still holds on to some low end torque and limits RPM potential. It will work, but the combo won't really be in synch. You'd run faster with a smaller cam, but if the car's stock now the heads and cam are going to make it faster, so that point may not mean all that much.

Get the AFRs if you can. They are the best heads hands down for nearly an application, and this way you still have them when you change the intkae and/or cam later on down the road.

 

I've dynoed similar combos. A 225/235 type cam will make 10-15 more HP below 5300-5500 and then the 235/245 type cam will make about that much more over 5300-5500, so it really is not a good tradeoff for any street car.

 

what rpm do you think it will make peak hp / tq. I will spin it up over 6500 if I have to
do you think that the 3500 converter will have enough stall.

 

I wouldn't recommend spinning the stock long block to that kind of RPM. I would be scared to push it to 6,000 to be honest.

Another issue with the cam is that it is a split duration, which with good aftermarket heads really isn't necessary.

 

ive been spinning it to 6300 with nitrous for a year now and it still has exceptional oil pressure and compression. if it pops the motor its not really a big deal. On the lt1 boards ive heard people spinning the stock short blocks to 6800 and their is not much difference in an lt1 and an l98 bottom end

 

You've never experienced any detonation. All it takes is one rattle and it will all go bye-bye. If you leave the nitrous jets as they came from the factory you will be fine, because they are rich (fuel wise).

I wouldn't spin a stock rotating assembly that fast, particularly one that was designed to go about 5,500, but to each his own.

If you ever tear down the motor I'd highly recommend studs in the mains, or splayed caps. The oiling system should be fine, as long as you've got 10 psi per 1,000 RPM it's sufficient. I'd also set the rod bolts with a stretch gauge and use high quality fasteners. Just some thoughts for down the road.

 

thanks for the advise its defintaly really fat on nitrous below 10:1 on a wide band
