Just read your swap thread. Very nice! I just acquired a donor vehicle for the same swap and did some searching and found this. Glad to hear you're pleased with the overall product and I'm looking forward to the same results from mine!
Couple of questions...
Was there much difference in the weight of the 2 engines and did it affect your front ride height at all?
Also, what about your radiator hoses, were they from a different application or were they of a similar application the 4.3l came from?
Thanks!
