my point was there is someone with a real ho unrestored with the worst options for drag racing, unprepared, running close to 13's . and will race any time anywhere. i could care less what u did on page 19. a lot of mouth runnin gets settled at the pure stocks..we will be there.

File this away in the FWIW file. I still have the timeslips from a couple of passes in my 71 TA, circa 1980, at Milan Dragway. Car description: 71 455 HO TA Automatic, no air, not many options, GR60x15 Radial TAs, stock exhaust, motor as built by PMD, but wait for it...2.41:1 axle! When I bought the car the axle bearings were wiped, so I picked up a junkyard 2.41 posi from a '75 TA.
Driver description: snot-nosed 19 year old that was no master at launch technique (although with a 2.41 axle it was pretty much stab and steer).

Best ET 14.66 @100! It went through the lights at 5000 rpm in 2nd gear.

Around the same time I had a buddy with a 74 SD Auto 3.08 car. We ran a couple times on the freeway from a 25 mph roll up to about 100 and they were basically dead even. His car was a little heavier with a/c and heavy bumpers, but also had the axle advantage. We both called it a draw.

Just a tease here but my buddies 455 HO is built, dyno'd and ready to be picked up at some guys house by the name of Jensen I think . It's for a GTO, not a bird. I hear it is strong We are cleaning up the engine bay, underside, setting up rearend with new gear and replacing parts that need it and will be ready for some pure stock racing this year.

How about some details on the performance? HP? Nice 455 HO 4 speed!!

Well, I can not find the email with the exact dyno numbers but I can tease you with that it is north of what Mark W. said back several pages ago that a strong 455 HO motor makes and north of what a certain SD motor of Paul Aragona's that he built last year. His GTO is an auto car.

I went back and looked to refresh my memory and Aragona's motor was making 534lbft at 3300 and 420hp at 5000 so it sounds like the new maxed out HO made in excess of 535lb.ft. of torque and 421hp? Would love to see the dyno sheet or know the numbers at various rpm to see how the whole curve looks. I'm continually amazed by how much power these relatively stock motors are putting out and at factory type rpm levels, congrats to you guys for pushing the limits on both these motors.

That would be correct . I am amazed also. The NHRA allowances really give this motor some help, not to mention the 2 1/2 inch exhaust system upgrade and with much better repro bias ply tires and a glued track they can lay down some fantastic times. Even with his motor being close to maxed out it was dyno'd with pump gas!
