I have a 1977 maverick that I thought would be better off the line. It will only spin the tires with brakes applied. It has a 302 with a mild cam, offenhauser single tunnel ram with a holley 600. It has the stock manifolds. C4 without a stall converter and 4.11 gears in the back with a mini spool. I have a hughes 3000 stall that im going to put in along with a new pair of hooker 6901 headers. Should these two help my performance off the line. I guessing that the tunnel ram is hurting my performance. But it sure looks good. It comes on pretty strong at about 2500. Any help would be great!
the problem is a mismatched combination. the offy tunnelram is for high rpm power not low rpm power (i think, but i may be wrong). you didnt mention what heads you have so i assume they are stock. the 302 is not a torquey motor to start with and when you missmatch the combo the torque will be even less. thats probly why it wont peel out.
intake is not what you need. if you want to keep the intake get your self a good quality stall 2500 or 3000. you will get good improvement if you go to a dual plane but if you want a tire burner you will probably need a cam with a smaller duration.
as you say, at 2500 it comes on strong. Torque con. when you put it in gonna be a BIG difference. My pickup had a 2800 con in it an smoked tires all day. I put stock in for towing an it was lots harder to spin with lower rpm con. Headers will be a nice plus! Gotta love the tunnel LOOK!!!
Yes that is the picture of the tunnel ram. Thanks for all the feedback, I'm guessing the stall will help. Probaly this weekend I will start removing and installing. If the stall and headers dont work, then I will take off the tunnel ram. It may look good, but I want the tires smoking off the line.
I have a very wore out 86 302 with stock cam, the only things it has are performer rpm intake and headers and it will easily roast the tires all of 1st and some of second. Your intake is killing you
good idea to put new seal in tranny with the convertor. I think you`ll be amazed at difference in the test run-er smoke!!! Good Luck
You have to realize that the stall you are installing requires torque to reach stall speed. By leaving that intake on you are killing the low end torque required to reach stall speed. You will stall the conv. at a lower engine speed. Personally I'd flip that intake over. put it in the garden and plant flowers in it. Now that would look cool.
i have that tunnel ram installed. it burns the tires like crazy, with 3:00 8.8 posi rear gears. but i have 282 solid cam, ported heads and a t-5 speed. the first gear make it rev quick.
tunnel ram and dual is great on an engine "built for it". gulupo could probably put a dual and still roast them. my mild cam (still stouter than stock) would dog. your stock engine would do way better with performer or performer RPM. either that or take the motor apart and build the rest up to where the tunnel ram is the bottleneck.....
