It seems I recall a 4.3 V8 by Chevy in the early 80s (Monte Carlo RWD, etc) that displaced 267 cubic inches. Is that the one? The only reason I say this is because the Olds 4.3 V8 numbered 260 cubic inches and the Pontiac 4.3 V8 numbered 265 cubic inches. About the engine you refer to above (L99), is it one that had longevity?

Oct 7, 2009 · L99 4.3L V8 has 200 hp @ 5200 RPM, 245 lb-ft @ 2400 RPM. 1994 L99's were equipped with either a 2.73:1 or 3.23:1 rear axle. '95 and '96 got either the 2.93:1 or 3.23:1 axle. The only real transmission difference is that the L99 …

Mar 8, 2008 · The 4.3 had a 95 mm bore, that's almost 17mm of metal between each cylinder. This is completely unnecessary for strength. It also makes the engine unnecessarily big and heavy (a lot of useless metal) for a 4.3 V8. If the idea is to create a 4.3 V8, a 102 mm (same as Northstar) or 103mm (same as 3.6 HF V6) will be a better choice.

Jun 17, 2012 · And, what it does for any larger RWD vehicles with room for a V8 (future use in SS sedan, Cad CTS, etc) is an open question--it's similar to my view of NASCAR's 358 CI rule, where 800+ HP and 9000+ RPM is the norm (unrestricted), while V8 Supercar uses a 5.0L (305 CI) package making 600+ HP with max RPM of 7500...different types of racing, with ...

Oct 28, 2013 · Adding to what Marky said, I think the 4.3 V8 was Chevy's standard engine choice just so that everything was interchangeable with the larger LT1- wiring harness, accessories, etc. Also the 4.3 V8 makes more torque than the 4.3 V6 simply because its got 2 exptra pistons N

Mar 25, 2013 · Despite trying to comply with Corporate Average Fuel Economy Standards that hearkened to 1950s driving styles and cruising speeds, even GM didn't ever dare combine the 4.3L L99 V8 with 2.56. GM tried to combine the 4.3L L99 V8 with 2.93 in a wagon. ONCE. There's a reason why the OEM .bin file for 1G1BL82W1RR100027

Oct 19, 2018 · ANYONE who tries to convince you that the 4.3L L99 V8 is capable of 'serious horsepower', is endangering your money. The long story, short, is that the most cost-effective thing you can do with the 4.3L L99 V8, is to replace it with a 5.7L LT1 V8. Put another way, a 5.7L LT1 V8 is MUCH cheaper than a 5.2L L99 V8.

Jan 14, 2012 · Nearly all 4.3L L99 V8 cars had one exhaust on the right, all 5.7L LT1 V8 cars had two exhausts. Nearly all L99 cars did not have 235/70R15 tires, most had 225/70R15, some even had 215/75R15. LT1 cars had 235/70R15, or 225/75R15.
