Party pulley

[mick53]

I'm having Gaerte Racing Engines building me a I6 292 with 4-71 blower and 3 Rochester 2 barrel carbs. I think the plan is about 5 pounds boost and pump gas for street manors. If I go play at the local drag strip and put a party pulley on the blower can I switch over to a separate fuel system with racing fuel so I don't detonate this very expensive engine? This engine cost more than my first house. This goes in my 53 1/2 ton pickup. Any thoughts would be appreciated. Thank you.

No suggestion but be sure to post pictures when you get it. I would like to see it. its going to look really cool in when you pop the hood.

They just got the block and head back from the painter. Global firethorn red pearl to match the body. Fenders will be black pearl.

What trans are you using?

Any thoughts about just running E85? Then you don’t have to worry about it. I think you can go up to 14:1.
So pending on your static compression and boost PSI you would be fine up to 10-12lbs of boost.
There is a chart on line that will tell you all that.
Good luck.

Upgraded TKO 600 with mid-shift kit. Frankland QC-80 rear end with gleason locker and bicknel torque arm.

I looked into E-85, my builder, Gaerte Racing Engines tells me the problem seems to be that the octane is all over the place at the pump. It varies wildly between region and batches. One low octane fill up and boom.

Look in to a boost timing master, they’re old school tech, retards timing based on boost level. I’ll try and find a pic. For instance at cruise I am at 36* but at boost (10#) it pulls 1* of timing per #. I run 91 octane. Most days.

Thanks, I will leave that up to my builder. They are using crank fired timing and no distributor. I presume the computer handles that but I will ask.
