Recent Straight-6 Gassers and Diesels?

Yes GM ditched the V6 and has been using a 4. 2L inline-6 in their rear-drive Trailblazers the last 6 model years, rated at 291 HP. Don't know how they are doing though. GM Vortec Six: CanadianDriver: Auto Tech - GM's Vortec 4200 inline 6-cylinder engine

I was secretely wishing that GM would adopt the 4200 I6 in place of the 4. 3L V6 as the entry level engine in the Silverado/Sierra 1500 during last years redesign. To me, it's increased power level compaired to the current V6 would have made a killer combo for a 1/2 ton.

No kidding, that would make a lot more sense wouldn't it?

I had the original 232 (from which the Jeep 4. 0 evolved) with stock 2bbl. carb in my Rambler American J/SA drag car in the 60's. It won its share and was a lot of fun.

Damn thats a great car and a hot lady and vice versa. I have a 80 AMX that is getting a similar treatment in the next year or so.

That Hemi-6 doesn't sound too bad at all. Check this out from the posted Wikipedia link:

265 in³ (4. 3 L)



The 265 was introduced in 1971 in the VH. It used a new cylinder block with a bigger bore diameter of 3. 91 in (99. 3 mm)—the same as many of the Chrysler small-block V8s—and a new cylinder head, having slightly more hemispherical shaped combustion chambers with larger valves.



The standard version of the 265 produced 203 hp (151 kW) @ 4600 rpm and 262 lb·ft (355 N·m) of torque @ 2800 rpm.



The top of the line performance engine in the E49 Chargers produced 302 hp (225 kW) @ 5600 rpm and 320 lb·ft (434 N·m) of torque @ 4400 rpm. The increased power is due mainly to a more aggressive camshaft, high-load valve springs, triple 45 mm DCOE Weber sidedraught carburetors, tuned-length exhaust headers and a higher compression ratio of 10. 0:1.

That engine would be a nice fit for my '72 Jimmy

Modification and performance potential



Even though these engines are old, there are still modern quests for more power. The already heavily modified E49 265 still has potential for even more power to be extracted by hot rodders, drag and track racers. Naturally aspirated versions are capable of making 400-450 horsepower and 360-390 ft·lbf of torque, with the best modified version revving up to 7000-7600 rpm in some cases such as Drag racing and historic touring cars in Australia.



Due to their robust design there have also been hemi 6 engines turbo charged capable of 8 second quarter miles. see Andrew Saunders, Justa6 centura.
