So here's my first post and I thought I would jump right in...
I have a NAS D110 (#169) in the Conejo Valley area of LA (North Malibu, Westlake Village area) and I'm considering replacing the whole drivetrain. The LT77 is starting to get notchy and the engine is lethargic. I'm looking at RPI Engineering 4.6 Cosworth recast motors (you know...the ones ECR WON'T SELL YOU) but at the same time, I have a buddy that is willing to give me (for FREE!):
1) A 5.7 shortblock LS-1 with 30K on it.
2) Accompanying 4L60-E tranny.
This is a hard call. For one, I'm sure it will be a major job but parts would MUCH cheaper moving forward. I have a mechanic that I know could do it but I'm concerned about a possible decrease in value to the 110. I'm looking at mark4wd.com,
GM Auto Trans and everything seems there but I have reservations. Can someone provide some advice? I'm torn between the free drivetrain and some costs on installation vs. expensive, new 4.6 short block with my ancillaries.
Some of my worries are:
Electronics & gauges?
Differentials? Can they handle the added HP?
Fit? If I have to modify anything on the car besides the drivetrain, this option is out. I'm not butchering my ride....
Thanks in advance for any comments or advice!
