Pontiac Engines at Rolex 24

While watching the Rolex 24 hours on TV, a number of the Daytona Prototype cars were running Pontiac engines. I can not find out any specific information on this type engine. I suspect it is a GM/Chevy NASCAR based engine with a sophisticated fuel injection setup but I am not sure. Is the fact that this race is held at Daytona and the sanctioning organization rules are "approved" by NASCAR for road racing series at their tracks that allow this engine to be run. Could this be something that NASCAR is evaluating that would be used in place of the present carburetors if they decide to change. Any information. Just curious.

To basic specs Of Daytona prototype cars..they are purpose built race cars with production based engines..Several different engines are used..I suspect the Pontiacs use a version of the SBC

pontiac

Oficially the last pontiac v8 rolled out in November 1978. The iron duke has been in every thing, by several names, chances are no. Iron duke is the tech 4, plus other names I don't remember, Used in S10- S20 trucks , calais, fords, Izuzs, and more. That only leaves 6 cyls. I don't know.

While I was attending the Daytona 500 this year, I went to the manufacturers display areas and they had last years Rolex Reily/Pontiac winner on display. I was able to look into the engine compartment and the engine looked like a SBC with Pontiac valve covers on it. It had the plastic intake manifold with multi port injection and the ignition coils on the valve covers. It looked outwardly like a stock SBC engine. There was no one technical there who could answer my engine questions. Over at the Chevy display that had an engine used in the Corvette (C6R ?) road racing car. They listed the specs for it. It was an all alum engine with a bore/stroke combination that gave it 427cuin. The only difference was that its fuel injection manifold looked like an old Hilborn unit. It had throttle bodies for each cylinder with multi port injection and had its ignition coils on the valve covers. Otherwise the 2 engines looked identical. Based on these engines I think fuel injection could be used and regulated by NASCAR if they wish to do so.

to many holes

H___no. Not unless each tunnel is alternatively intake-exhaust,etc. A blow up lost detail. looks cool-Iam 55 and got old a little while. Any way you go, and all others I ain't forgetting 426 hemi's and 427 or even 351 Clevands, mor sbc have been are out there than anything else,if something didn't happen while I was playing RIP VANWINKLE. I want a 4 cyl, DID I pick the wrong engine. I am looking at more than torque and HP. Can I get parts for in 10 years, Can I make Parts?. I am looking for a 4 cyl engine, that is dependable. My state does an inspection, But not a emission check. We can play with cam, timing, air/fuel ratio , etc. Bodies, frames, you name it. I am not stupid,but I have been at a light where Youshould wait on traffic, not turn the wheel all the way, and pop the clutch at 6000. I was looking at a MG T car on VW floor pan. Salvage the fiber glass, and get out the welder. Educate me, on 4 bangers.

That's the LS series engine in that picture. I thought that might be what you saw and mistaken for an original style small block.

You are correct. I use SBC as a generic term for all versions of the new LS engines as well as the original style engines. Sometimes old habits and thoughts are hard to change. Thanks.

I quit when the big engines went out. Bought someextras, Icould use a 455. But I am looking for a 4 cylinder. Was all the hype about the iron duke capability wrong. It do that well out of the factory, but it was supposed to be ready aftermarket. What is the rod length, and stroke, all the manuals, handy are to old. Any Ford fans- I have a friends branco 2 We want to fix and sell. I have refused to learn anything about fords- paids 20 bucks for a book.Last Ford I took apart was the straight 6 that had oil probems. ma
