I thought your combo was probly close to mine. You are turning more rpm because of the shorter stroke and smaller engine. I think my car will run very close to the number your car is running once I get all of the bugs worked out. So far the car has gone a best of 10.21 at 131.51 with only a 1.51 60'. The car has gone a 1.478 on radials and 1.4706 on 10.5X28 M/T ET Drags. The 1.47 60's were done with 3.90 gears, I have changed to 4.30s and the 60's have slowed down the best currently after a lot of work is a 1.51. The car was only running 10.41 at 128 when and was making about 50 hp less at the wheels then. I am going to change back to a set of 4.10s to hopefully get my 60's back into the 1.40s. My combo is a EFI 364.
4.135 bore
3.4 stroke eagle crank
5.4 H beam rods
Ported Twisted Wedge heads
Ported BXR intake
custom cam with comp cam lobes
254 in. / 264 ex.
.672 lift in. and ex.
208 intake center line 208 LCA
1.6 com rockers
1 7/8" Kooks headers
90mm TB and 92mm MAF
C4 trans with trans brake
10" convertor 4500 rpm stall that is actualy stalling to 5100 rpm.
The car was around 2840 with me in it, but should be around 2930 now, I added some weight and have not weighed it since.
had 3.90 gears currently have 4.30 gears, going back to 4.10 or possibly back to 3.90 gears.
