Guess you have never had a newer engine that ran, poorly but never gave a CEL.Actually the modern motors are easy to work on because of the sensors, retrieve the trouble code and youre on your way to fixing the problem. The modern motors arent bad to look at if you take the time to dress it it up, just like any other motor. I've seen some pretty nice looking LS motors.
That's what I've got in my 69. Crate 502, upgraded cam, aluminum heads and intake, dual quads, 3" headers with magnaflows...I'm putting out better than 650 RWHP. Easy drop in too.I'm on my second z06, but neither car has (had) the sheer acceleration of a factory 502 bb.
Change the heads/cam on the 502 and 500hp --> 700hp. Also, it's an easy swap in a c3.
A word of caution, all that torque can break rear ends and axles that are 30 yrs old. And if you have nice body work, try to stiffen the frame, as it twists and the body work/gaps get messed up. Also, my one car always got cracks around the headlight openings.Well I guess it's time I chimed in. I made the decision to install a modern day BBC 496 completely stock from GM, a donor engine that was used in pickups, motor homes and box trucks. It weighs a bout 700 LBS and I couldn't care less. I'm not going racing and I want beat a Vette to death that I have spent my hard earned money and very long hours on. That being said, I wanted something different that no one else has. Something modern that will make me smile when I do hit the gas. I know it's not for everyone but it pleases me and that is what counts. I love the fact that I can get in it and it cranks and drives away without stumbling before it warms up. I like the fact that it will get 14 to 17 MPG unlike the old BBC that get 6 to 10 MPG. The best thing about it is if I dont like it I can install it in a boat, generator, water pump truck or anything else that needs monster torque and drop a LS in the Vette.:
So here's to the BBC 496 :cheers:
