Default 502 Ram-Jet Crate Engine Bracket Racer ?

My wife & I have a 2500 pound tube frame altered set-up for a Big Block engine. We Bracket race at a 1/8th mile track with questionable traction.
We do not feel the need to be the fastest guy at our track. Does any one out there have any experience with one of the 502 Ram-Jet factory crate engines, Bracket Racing ? Several years ago I diassembled a 502-502 Crate Engine & Had Chapmans in Salt Lake City Mildly Port the heads and intake manifold. I Squared the Block Decks, Bushed and Bored the rods center to center, Honed with torque plates, Balanced, Reassembled engine complete with G.M. 502-502 Cam, Pistons, Carb & Manifold. It made 585 on the dyno. That is plenty of power to do what we want with this car. The unknown is the Ram-Jet F.I. Unit. Any Constructive Help wil be appreciated.
Thanks Larry D

Larry, bracket racing is all about keeping it simple aka KISS and the formula that works is overtired and underpowered as well a glide and a single 4 barrel carb.

That said, I've been bracket racing for 20 years and have yet to see one 502 Ram-Jet GM crate engine in any bracket car in any class. First and foremost is probably because for $11,000 you can buy/build a far better bracket engine.

You can build a decades proven 468-496 that will go hundreds of passes before needing to be freshened with nothing special factory cast iron heads, a victor jr. manifold and 850 carb that will make anywhere from 600 to 700+HP depending on the heads, cam and compression and you'll have money left over.

Default Re: 502 Ram-Jet Crate Engine Bracket Racer ?

Just a quick note to say. I have a small machine shop in the very middle of nowhere. Several years ago I ordered a Ram-Jet 502 Engine for a Customers Car. The Ram-Jet F.I. Unit would not fit under the hood. Because it came installed on the the 502 engine once it was removed from the engine it was un-returnable. So I purchased all the 502-502
Hardware from G.M. to make my customer happy. I was stuck with The Ram-Jet F.I. Unit. I havent been able to sell this unit and Its a Novel idea and I have all the parts to do it . Every Hot Rodder out there knowns what the E.C.M.'s have done for Engines in General. I am just asking can that also be a good thing for Bracket racing ?
Thanks Larry D

There's a reason why you haven't been able to sell it and No!

You're not building an 800 HP 468-496 using factory cast iron heads from oil pan to carb for under $11K

I have, I would build them nonstop intake to pan for 11,000. Believe it or not its pretty easy to get 800 out of a 496, the down side is the power peak is on the low side.

I did say oil pan to carb and I kn ow what's required to get an honest 800HP out of a 496.

That said, you'd have a hard time convincing me and many others that you build/sell a 468-496 using factory castings that makes 800HP, proved on the track for $11K.

We know Johns been 138.3 @ 3615 in 800 feet air with no tuning with 32 degrees timing, this 10.7 compression engine made 774 on my dyno, I think its shows the power, another point of compression pushes it over 800. I wouldnt want to include the carb for 11,000.
