Randy,

Numbers from the 60's and 70's were rated differently than todays motors.
The L88 and old school LS7 were more or less all out factory race motors. Look at todays little C6 ZO6 motor that is 427ci making every bit of 505hp from the factory. Smooth idle, runs vacum brakes, weighs less.. With a set of headers and a cam swap, they have been known to make over 600rwhp on pump gas.

Tony Mamo from AFR recently made 730+hp on an engine dyno with a 454ci LS motor. This was a 91 octane drinking hyd roller motor.

I mean really, things could be argueed for days on this.


I still haven't seen a rough cost for an NA high 11/low 12 second big block in a 36-3800lb truck.

4-5 years ago I remember driving around my buddies big block 69 truck wearing aftermarket heads, decent sized cam with 11-1 compression, converter, gear and tire. I was only running 12.30's in my truck then. He gatted me by 2-3 cars do to my lack of traction, went by him before the 1/8 and strapped close to 5 cars on him. Similar results with a second pass. My guess is it was a high 12 second truck at best.

Now I know DJ's old motor would have drove around me.. But what would that motor take to replicate in todays market?
