Is a 4.8 Gen III motor to small?
OK guys,
I have a 4.8 and 5.3 with all the associated swap pieces to swap a gen III into my 67 truck. I am going to sell one of the motors, So my question is, is a 4.8 is too small for a 67LB 3/4 ton 4x4? The curb weight is probably just shy of 4500 lbs. I believe a standard 2wd 1500 is about 4000 correct? I also have a spare 5.7L crank, I could re ring and bearing the 4.8 with the rods and crank to make it a fresh 5.3, or .....should just put a LS1 cam, the headers in it and go? I am thinking it "should" have close to the same HP as a stock 5.3 with the headers and cam correct? Anyway, I have way to many Gen III parts and too may options! Here a list of parts, please chime in with some good feedback and give me some ideas. New 6L long block Bare 5.7L (3.905 bore) block with forged Diamond pistons Complete 4.8 Mid mileage Complete 5.3 Low mileage GMPP Carburated Intake GM Hot Cam Stock crank ARP main studs LS6 stage II or III heads (I forgot who's) Crower Maxlite 6.20 rods Stock 99 LS1 cam Stock 2000 Cam and 01 cam The 6L is going into my 67 Camaro with one of the 4l60's, main studs and the Stage II/III heads cam and a wet kit. The hard part is should I put the hot cam in the 5.3 and put it in the truck, or use a stock LS1 cam? Then should use 5.3 as it is and try and get a few $$ for the 4.8 or should I build the 4.8 as a 5.3, use it and sell the 5.3 as a complete motor? This is giving me a headache, Thanks. Mike |
