Ran 12.61@110.54 last night. 1.73 60ft. I'm thinking that's about all I'm going to get with my current setup. I think I need a roller cam conversion a little head work and a higher stall to get 12.0 to 12.2's. DA was bout 700 last night.

Not bad for the cam and stall. Could use 3600 stall or so and then possibly a bigger cam. Roller be nice for more lift

Yeah, a conversion to XFI268 with 1.6 rockers a little bowl and valve work and a bigger converter should get me there.


I realize that the roller cam puts out more everywhere than the flat tappet but the XE 268 is a 224/230 477/480 and the XFI is a 218/224 565/570ish im concerned about going down in duration with the roller. Maybe I shouldn't be?

I would get the custom grind 224/230 xfi lobe spec on a 110
Will need to change springs in heads

Why on a 110?

More low to midrange on the big heads

I think this is yours... I found it on TRP's FB site:

FWIW, I was going 12.00-12.10 at 110mph at Thompson & quaker at 3580#. How is your suspension set up? with that mph, I think your making horsepower, just need to work on the rest of the car. I went from 12.40's to 12.0's with the right suspension setup and converter, and the mph was 110 for all of it. If you knew what I had for motor, you'd laugh.

Yeah that's me at TRP!

My suspension in not totally ideal for drag racing but I have no wheel hop and im hooking just fine with the drag radials. I have eibach 1" drop springs KYB struts and shocks. All poly bushings and links. Bigger front and rear sway bars etc. I do have a crappy B&M 2400 stall converter which is what I think is really holding my E/T's back. I think a 3500 Edge or Vigilante would be a huge improvement.


What motor setup are you running?

no green

Oh yea, those b&m's aren't the greatest. Look into the Freakshow's on Ebay. I replaced my b&m 3600 with one of his 4200, and that was the biggest et drop I ever had. I have an FTI, now, and it's better yet, but there's a $500 price difference. Whatever you go with, I think a converter swap would gain you more than head work and a cam, assuming you can hook it up.

My engine's just a stock crank 2 bolt, wore out ported double bumps, 11:1 comp, and a miss matched solid roller. It probably only makes 380 horsepower on a good day, but it loves nitrous! I went 11.75 at 115 on motor first pass this year, 3580#. The rest of the passes I've been playing with a 100 shot on a timer trying to run 11.50.

The right roller can should give you more power all under the curve due to the increased lift and more aggressive ramp profiles.

Don't be afraid of losing some duration - you will gain just by increasing lift.

In my 84, I am running the Accel 219/219 roller with CNC L98s and a performer RPM (with the stock CC carb). Peaks out at 5500 or so and 400hp and 425lb-ft, giving a power curve you can't get with a non-roller. You will probably be in the same range - maybe another 10 or 15hp higher.

What E/T's are you running in your 84?
