OK give us the poop.
Cubes? Horsepower? Fuel Injection?

Re: The New And Improved Avanti Motor!!!!!
 

HP- expected at least 600
CID- 496
Computer- accel so yes it is injection with enderle stacks.

Nice!

Re: The New And Improved Avanti Motor!!!!!
 

What did it start out as, a Merc496? I have a HP3 496 and was wondering what I could do with it, will a carb and intake fit on it and are the headers the same bolt pattern as a Gen 5 block. I havnt been able to find any parts for it if I wanted to remove the fuelinjection.

That's pretty! :drink:

Re: The New And Improved Avanti Motor!!!!!
 

Eddie the the new GM 496 engines including the HP3 are not good candidates for more than 600HP without new internals. And I don't believe you can convert to a carb either; remember distributer-less ignition, coil packs for each cylinder, you need the computer controls.
If you still have your HP500EFI, that is the engine to boost; and I do mean that literally. Lots of supercharger packages to bolt on that baby to make 750+HP... :drink:

I guess when you get that baby dialed in she'll run mid to high 80s... :evilb:

Re: The New And Improved Avanti Motor!!!!!
 

Very nice Johnny, your product ( motor pkg ) looks great.

Re: The New And Improved Avanti Motor!!!!!
 

Thanks Pat, I just don't like racing with a blower, I do have the hp500, that I may sell to Ale with the Activator, May just build a new motor from scratch do you think the headers on my HP3 will bolt to a Gen 5 block, I would think so. I was thinking about change the 496 to a carb with a distributor conventional engine, maybe thats impossible. Does the engine above have a distributor?

Re: The New And Improved Avanti Motor!!!!!
 

If you don't sell your HP500EFI, it is a good base to build a 540cube NA stroker with 650 to 700HP engine. The AZ Speed intake/fuel injection can be altered to handle the power.
If you are looking for more than 650-700 NA, then I would suggest you start from scratch with a tall deck block.
Yes, I do believe the headers from your HP3 will fit the older style engines.
No, I don't believe there is a distributor drive mechanism design into the new 496 big block.

Re: The New And Improved Avanti Motor!!!!!
 

NO IT WAS A stock 496 chev. It had GM aluminium heads.
Thanks Guys!!!!

Re: The New And Improved Avanti Motor!!!!!
 

Where do you buy 8 USCG approved flame arrestors for those stacks?

Re: The New And Improved Avanti Motor!!!!!
 

The same place the Turbine guy buys them. LOL

Re: The New And Improved Avanti Motor!!!!!
 

:eek:

Re: The New And Improved Avanti Motor!!!!!
 

The GM 502 is rated for 750...


MAX!

Re: The New And Improved Avanti Motor!!!!!
 

Johnny, how much HP does the 525/502 end up with after a whipple aftermarket kit ???

Re: The New And Improved Avanti Motor!!!!!
 

Around 750. The HP 500 with a whipple installed by us makes arond 715 with the stock motor.
