Will my 700r4 hold?

I have just built a 355 chevy, with an all forged bottom end, flat top pistons (10.75:1), pro lightning 220CC heads, 268-H Comp cam, victor JR intake, 750 Speed Demon, 1956 Chevy 4 door wagon (3400 lbs), 3.55 rearend gears. The trans was rebuilt by a reputable trans shop, but at the time, I just had a crate 350, so did not have anything really special done to it. I plan on getting a trans cooler ASAP obviously, but is it possible the trans will hold it? Thanks in advance.

Kyle

It should , your intake don't start making power till about 4000 rpm, and your carb is too big. So I would think it will be mighty sluggish on bottom end.

dgcantrellsr,

I now only have a 600 CFM EDL carb, and I forgot to mention I have 1.6 rollers. How much power do you think that it might even have?

Well, are you just going to cruise and punch it out on occasion or will you be hitting the dragstrip every weekend?

Either way I would leave it in, it was just rebuilt so it should take some abuse for a while.

I think the top end of your motor is geared more to the drag aspect , big valves, big runners, high rpm intake, as for power , I don't know , but I do think it ain't gonna have much bottom end ,your cam is 1500-5500 , intake don't start making power to about 4000-4500, Most of the time bigger is not always better. Also it would depend on the converter stall as to the bottom end performance ie HAMMER DOWN ! JMO

This is pretty much how I got the motor. I was planning on doing an RPM air-gap, but can't for the angle of the heads. Also, I do plan on having a cam custom ground for the motor & car, because that cam is going to hold it down alot! Any other suggestions from any of the masterminds in here, also maybe a cam suggestion? I was thinking Comps 280, I don't want to go too radical, probably no more than a 294 or so.
