It's an incredable engine. A real "truck" engine and designed as such. 496ci, is a bored and STROKED 454. Roller lifters. Fuel Injection. A 454 is 4.25 bore with a 4 inch stroke. The L18(GM designation) is a larger bore with a 4.25 stroke. Stroke means torque. A 455 olds is under square,ie. more stroke than bore. I considered it but went with the Caddy because of the fabbing of the pan, block adaptor and oil pan. I'm an electrician. Daves a toolmaker. His intallation(haven't seen but photos)is first rate and really nice. Might be at Duquoin, come see it.,,,,PL

Howard,
I agree with you vis-à-vis the hot rod 454, it would depend on the cam
Cameron selected.
The 8.1 engine puts out 411 foot pounds of torque at 1200 rpm!
Here's a link to the torque / hp chart.

I had the pleasure of driving Dave's 8.1 and I can assure you that it GOES!

You need low end torque and not high end H P.
Yes its a Hot Rod with plumbing, but not that kind of Hot Rod.

Here are the number on our 455.
Torque 464.0 at 2200 rpm, 477.1 at 3100 rpm
H P 349.4 at 4600 rpm.
With our rigs we don't need no "Stinking Horse Power"
We need Torque.
So why spend the $'s on 454.
Yes if I where building a street rod I may look at a Chevy B B engine.
Or a Cad 500 also a North Star engine.
As for now I'll stay with Olds.
We ran 455 jet boats and kicked some A** in the 70's and 80's on the lower
Colorado river.
After that the big out boards came along and started to kick our!
