I found a very interesting thing yesterday that I did not think was true. My LPE 385 with intake cams is faster than my stock cam'd 415. I would have never thought that from driving them individually. My son and I drove them both. The 385 pulled or closed on the 415. Both have 4.10s. The 415 has 18" (vs17") wheels, but it was compelling.
Long live the king. Neither are slow. Ted |

Right or wrong, I left the car with stock valves and stock cams. The driving impressions of the LPE 385 (intake cam, stock valves, 4.10s, headers, dual mass), HAT 415 (stock cams & valves, 4.10s, headers, dual mass), and HAT 415 cam (LPE Stg 2 cams, big valves, 4.10s, single mass) are very different.
The HAT 415 has tremendous low end torque compared to the cammed cars. It feels fast and is a great around town driver. The tune is almost spot on. It drives like a 600hp stock ZR-1. The car has coilovers that ride very well and is lowered about an inch. The LPE 385 does not have a great low end but comes on as revs increase. It has always felt a little slow around town as I don't use all 7k rpms. The tune is very good on this car and drives like a totally stock car. I never thought it would run down the above car. The 385 was done right off of the truck in 1995. It has stock suspension and really transfers weight better on acceleration than the coil over cars. Then there is the devil. The cammed 415 is brutal. The tune has poor drivability but works at WOT. The engine had to have a rebuild...so upgraded heads with big valves. The car lost a lot of low end torque after. I think the compression ratio was lowered much to my chagrin. But, wind it out and it's a monster. The coilovers lower this one about 2". Weight transfer on acceleration is not as pronounced as the others. I'm not sure which way I would go if I were to start over. Ted |

I know this thread is quite old, but I just stumbled across it now. Impressive collection!
If you ever wanted to part ways with one (just one!), I'd be interested. |
