Tubtar,no need to take out the tortionbars to install TTI headers,all it takes is to read the instructions,use alitle comon sense and hope the car was built right in the first place. any specs on that engine,i suspect its a W-something..
O.K. , I thought I read that early A's had to route the torsion bars through the headers.
My deal is a 405 inch W9 / R-3. Fairly mild solid roller 264 @.050 and .664 lift , and 12.85:1 , built for E-85 and occasional street use.
I was going to dyno it this summer before it went in the car for the last time , but I have had so many set backs since I started this deal that I lost all patience. I will tune it on a chassis dyno as soon as I get it finished......hopefully in time to get a couple months of racing in before the snow flies.
