My point is, the LT5 was severely under developed upon introduction...obviously. And, to point this out, the 3rd gen LT5 intended for the 1996 MY made 550 hp from that 5.7L block when the plenum was opened up similar to what experimenters had accomplished in the interim. (And, did I mention output improvements were NOT at the cost of drivability???)
The LT5 is truly a remarkable motor, and it just kills owners like us to think of what could be if only GM would take the lead again and develop it as (at least) a 6.2L DOHC. A TT, 6.2 (or dare I say 7.0L?) DOHC in a mid engine (awd?) Corvette would once again be a world beater (as the C4 ZR-1 was at its introduction)!
I can dream, can't I?....
YOU need to join the fun!  |
That is great information. I finished reading
Heart of the Beast not too long ago and recall that the potential of the LT-5 had not fully been achieved. I’ve wanted a ZR-1 since 1990, I remember seeing my first one parked at a popular Ocean City, MD restaurant back in the summer of 1990. The red Z was a sight to behold. The input and advice from Registry members has been very helpful, my hat is off to all of you, the amount of knowledge here regarding the LT-5 is impressive.
I have decided on the color I will pursue, going to go after a Polo Green/Light Beige combo (it’s what I have now). Because I’m targeting a ‘94 now, I am moving myself up in the amount of cash outlay to the high 20 range. Going to a ‘94, I will need extra time to save for the shift, but I will be in a Polo Z at some point.
