Was the 7.4 offered in one of the cars on the VPI list (not including high performance /special edition models) https://www.chumpcar.com/downloads/VPI_Table_Dec2016.pdf if it is in a car on the list, you are allowed to run it.

Are you saying:A Chevrolet 3rd generation small block Vortec 5300, or LM7/L59/LM4 does not come in any car on the VPI table. Does anyone know if I can run any big block Chevrolet engine with 7.4L of displacement? _____________________________________________________________________________________________________ If the above is what you are saying, then I see many 1970-1975 Chevrolet vehicles on the list you could use for the basis of an engine swap. If you are asking about the Vortec 7400 ( L29/L21), no vehicle on the list has the engine from the factory.....as far as I know. Is this what you were asking? Did I answer your question? What is a 4200? I am lost........................ Quote Link to comment Share on other sites More sharing options...
mender Posted March 24, 2017 Report Share Posted March 24, 2017 I think he's saying that with a 5.3 swap, the car that he's thinking about swapping is 4200 pts and with a '70s 454 (Caprice, Impala, truck) is (as a guess) 243 pts. I think the best way to make sure is to email Mike or Phil and get preapproval of the swap. On the same topic: the swap rule states that the highest VPi version of the car is to be used for the base VPi before the power to weight is accounted for. In the case of a high performance or special edition car that was offered from the factory but isn't called out on the VPi list, is it the highest VPi on the list and any "adjustment" points for power to weight? No 50 pt swap penalty since the car isn't actually getting a swap but the same PWR penalty points? Seems to me that would be fair and should keep the intent of the PWR adjustment/ceiling without adding a swap penalty to a non-swapped car. 1 Quote Link to comment Share on other sites More sharing options...

mender Posted March 24, 2017 Report Share Posted March 24, 2017 I used a '74 Olds Cutlass with the optional 455 4bbl engine. The VPi doesn't go back far enough for that but knowing Bandit's preferred car brand ... 1 Quote Link to comment Share on other sites More sharing options...

Team Infiniti Posted March 24, 2017 Report Share Posted March 24, 2017 (edited) Indeed, build it and bring it! ( provided 4200 LBS is allowed ) Is this an exercise on how to go broke buying brakes tires and fuel?

thomasp Posted March 24, 2017 Report Share Posted March 24, 2017 (edited) The VPI Table includes Chevy K/C series Truck up to 1999 7.4L 1988–1995 230 hp (170 kW) @ 3600 RPM 385 lb·ft (522 N·m) @ 1600 RPM 1996–2000 290 hp (220 kW) @ 4000 RPM 410 lb·ft (560 N·m) @ 3200 RPM Edited March 24, 2017 by thomasp 1 Quote Link to comment Share on other sites More sharing options...
Bandit Posted March 30, 2017 Author Report Share Posted March 30, 2017 The above from Thomas. Yeeeeeeppppp In a 75 Monte. Which came with a really weak 454 stock... Around 160hp. Would have to look it up, but no way Chevy built a Monte with more HP than Vette. Quote Link to comment Share on other sites More sharing options...

Yeah, more than just compression is different there. Had a 70 Deville ragtop with the 375hp 472. At 5000 pounds it still smoked a few supposed musclecars. With 2.93's. 525 torque helped. Lighter motor than the Chevy BB btw.... Edited March 30, 2017 by Bandit Quote Link to comment Share on other sites More sharing options...

Unleaded at 2.25 a gallon is the least of my worries after entrance fees, driving suits, cage, fuel cell, helmets, etc. Edited March 30, 2017 by Bandit Quote Link to comment Share on other sites More sharing options...
Bandit Posted March 30, 2017 Author Report Share Posted March 30, 2017 I just like the fact no one has said it's not legal. Picking the starting point up tomorrow. 22 gallons stock sounds great, but it will still be a struggle to make 1:50 or so. Miss the 7 hours races at RA already. Helped fuel hogs...Probably why they got rid of them. Poor choice in my eyes. Fans like to see the fastest car win. 1 Quote Link to comment Share on other sites More sharing options...
Bandit Posted March 30, 2017 Author Report Share Posted March 30, 2017 (edited) Btw Anyone here on the forum know anything about the old ass 72 or so Grand Prix that ran at RoadAmerica a year or two ago? From vids it looked damn impressive for something that rivals a Tiger tank for weight. Seems I saw something about some GM engineers on that team but may be mistaken. Curious about drivetrain as it looked competetive cornering. Edited March 30, 2017 by Bandit Quote Link to comment Share on other sites More sharing options...
