Roasted my 700R4 yesterday, now I have to decide what to do for the rest of the year. This car has gone 10.90s@124 so far with the 700 & D-44 rear muffled. Now that I've broken both of them its time for a change. I love the 3.06 first gear of the 700 but I need something that will live longer.
This winter the car will get a 9", coilovers & a 4-link, solid roller, etc. Right now I want to be able to finish out the drag racing season without breaking the bank, these are what I'm considering.

Thanks for your input guys, Dave

Dave, I cast my vote for the TH350. I don't think the tech inspection ***** will allow a transbrake in a footbrake class. :nono:

I've been thinking about a Turbo350 with a lock-up converter. I want to still get decent gas mileage, and be able to run sticky tires.

I haven't looked into the swap, or anything like that, but thats just what I want to do.

BTW, the guy that rebuilt my 700R4 guarantees it up to 600 hp, I haven't tested it yet though, I'm only making about 300 hp/450+ lbs of torque.

 

What have you done to your car that I haven't seen? 450 ft/lb should be about 369 at the wheels with a 700R4. Thats a poopieload.

 

I've always liked TH-350's...You'd need a torque beam adaptor, but it'd be worth the effort...

...Lots of pro-built drag 350's fairly reasonable...And TQ's to match...<drool>...

 

Scorp, the torque is purely a guestimate. The 300 hp is probably an over-statement. The torque should be close though, the stock induction is ideal for making torque. By maximizing air-flow through the (mostly) stock TPI, adding a cam that only opens a little bit, but for a long time, with a mostly straight exhaust. I haven't been able to test it(dyno), but the Car makes an ungodly amount of power off of idle. If you stomp on the gas, the rear end will pass the front end. If I ease into it, she really lifts the front end.

However, this setup is less than ideal for racing. I thought I had found a cheap way to make a lot of power. Well, the power is here, but only at a very specific rpm, its like a Diesel. With the intake manifold cut the way it is, it makes a lot of tq, with only a little bit of hp. The car completely dies around 3,100-3,200 rpms.

I've pretty much given up with trying to turn it into a race car as is. The motor that is in it now is great as a daily driver, very tame unless you get on it. Passing, and off the line are fun, and economy is actually better than stock.

The next two years, she's going to stay mostly the way it is, mechanically speaking. In order to fix this motor to make it raceable, would take a whole lot of work, the cam just doesn't work with the aftermarket heads available. My plan is going to be a 406 CI motor, Canfield heads, pretty crazy cam(not decided yet, but probably around .525/.530 230/234), with a Holley Stealth Ram. The motor thats in the car now will hopefully go into either a circa-1970 Chevy pick-up, or a 1988-1997 Chevy pick-up, just to be a tow vehicle with a little bit of pep.

To sum that up, yes I make a lot of torque, but no, it doesn't make the car fast. Fortunately it hasn't eaten the new 700R4; yet.

Where did you find out about the torque beam adapter? Have any info?

Thanks, Dave :yesnod:

 

Pulling the 700 today for a rebuild, here's hoping it'll make thru the season.
:rolleyes:

 

Why would you throw a TH350 into a road car? That'll kill your interstate fuel economy unless you add the GV overdrive unit like Bob did to his.

I can't see losing a ratio and having to roar down the highway at 3000 rpm, unless you're going for a pure drag car that rides a trailer back and forth.

Correct me if I've a bad misconception of the TH350 - it's a three-speed close ratio, right? Rotten final-drive revs for a road warrior's car.

 

Matt,

Your points are valid for the street, but actually drag racing is the primary concern for this car.

Thanks,
Dave

 

Can always look into the 200R4 swap also... correctly built there are many a heavy weight GN going in the low 10's with them. The internals are stronger then that of a 700R4.
