That shouldnt be long. I destroyed my 2.76 7 1/4 pegleg in just one year behind my 318 with just the following;
Lunati 10200701 cam
Performer intake and 600 cfm summit carb

And only stomping on the gas at every second stop sign.

Don’t want to turn this into a rear end thread but you might be surprised. Mine last years behind my 360 including trips to the drag strip.
