The little 355 just doesnt have enough TQ IMO with that clutch and tire size up to keep the front end up NA. I was having the exact same issue.

I do have a chassis mount torque arm.

Came up with a fueling issue today on the way to the dyno so I have to figure that out.

Car is only making 20psi fuel pressure now. Doing a full fuel system, and a TH400.

You were complaining that it didn't fit well in another thread. Were you having trouble shimming it?

Like I posted before... he needs more wheel speed to keep from bogging the motor. He has plenty of torque if he gets the shock settings right. As for stock suspension working better than suspension for an 8 sec ride... I wouldn't be blaming it on the lack of torque. On a side note I have some SA QA1s for the rear I'd gladly trade for some DA Afco or Strange

Greg The TH will work much better for you!

Wicked the 355 has enough TQ to go fast just not with that clutch/tire combo to get the wheel speed up enough and If he gears it lower he will be in 5th threw the traps worse than he is now. A 27 or 26" tire would help alot NA. The car was working good on spray till it ran out of gear.

Converter is ready to ship. I'll be out of town working for two weeks but when I get back, trans should be built, fuel issue should be squared away, NOS Mini Progressive should be working correctly (wasnt last outing) and we will get some shakedown times with the auto trans in place!

Oh and lightweight spool and 3.73's

Hoping I can go 11.80s or so N/A and deep 10's on the same shot as before.... then start tuning up the wick and look for 9.90s....
