Would you.... 402? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**argonaut** · 08-17-2009, 01:43 AM

I might have the opportunity to get my hands on a 402 out of a 1-ton camper, if my dad ever gets his hands on this particular donor truck, and if he's feeling generous (he usually is

).

The question is: Would you go from a 350 to a 402 in your Blazer?

I'm afraid of decreasing fuel mileage. I'm also afraid of bolting it to a TH350, though the motor would come bolted to a TH400. Perhaps I'd just need to find the right tail-housing to bolt up to TH400 to my transfer case?

Any disadvantages?

Where would I get mount brackets for a big block into a 4x4?
