Road Kill Gremlin/500

Ditto to the above comments!

To borrow from the lyrics of a beautiful song, and from scripture, “help my unbelief” that those guy have a clue at making power with a 500 Cadillac engine.

258hp plus 20% driveline loss is 310hp on an engine dyno. Cadco has dynoed stock 1970 500s at 323hp and stock 1975-76 500s at 303hp. These guys just put down stock numbers with a carb, intake, headers, cam, roller rockers, and who knows what else. Then only added about 85rwhp with a 150hp nitrous kit.

On the plus side, maybe it will scare some of the bandwagoners off and we’ll get back to being able to get speed parts when we need them instead of standing in line with a bunch of people who won’t even be in the game in a year.
 
It also had CNC ported heads and 2.11/1.88 valves.

Did you see all that blow by on the dyno? And I never did see them take compression readings on that motor before they dumped all that money into it. It might have had 1 or 2 dead cylinders. They never even degreed the cam in it. They only took one pass N/A and one pass with nitrous. It's like they gave up on the project half way in to it.

I checked the episode on what cam they put in from Summit, They said: 0.520" and 234 degrees at 0.050 intake and
0.504" at 249 degrees at 0.050 exhaust; I checked and it matched up to this one at Summit. https://www.summitracing.com/parts/cca-94-601-5/make/cadillac . This is one of those sh.tty thumper series cams with 107 degree lobe separation that makes your car sound mean but run like sh.t with no power. Probably the worst cam you could have picked to move a 6,500 # hearse.
 
We’re they running the stock pistons?
If so, what year design?

According to the vids stock bottom end. And same year engine. STILL doesn't compute. I think Sherman needs to slap Mr. Peabody. Oh, and one more thing :crap: :crap: :crap: :crap: :crap: :crap: . Sorry. Six more things. Oh, did I mention :crap::crap::crap::crap::crap::crap::crap:!
 
Just goes to show that the right combination of parts is what matters. I'm learning the slow way that bolting on a hodgepodge of hotrod parts does not make for a fast car.

Good lesson to learn. That realization will save you money and frustration.

Best,

I know this is a bit old, but did anyone else notice how little gain they got when they jetted it up from 100 to 150 hp? It's possible to spray enough nitrous that an engine has trouble ingesting it all, but that wasn't happening there. Hell, I'd have STARTED at 150 hp and gone up from there.
