Need Fuel System Help 3.8 to 4.3
My kid is taking out his stock 3.8 on his 03 and putting in a 4.3. Where he bought the engine they recommend 24 lb injectors but I'm trying to figure out any other fuel system changes we need. Haven't been able to get answers from the engine builder. Trying to figure out if the fuel pump and fuel rails need to be changed, what size MAF and anything else.
The engine specs are:
4.3L, 9.5 compression, Cam .480/.480 204-216 @.050, intake valve 1.892, exhaust valve 1.491.
Also, I'm having a hard time finding 24lb injectors for the V6, find a lot that come in sets of 8 for the V8. Would injectors made for the V8 work on the V6, see a lot used on ebay.
Would appreciate any help advise, this is the first V6 we've built.
