478 custom flywheel
Hi guys my first time posting I have 63 k1500& I ran across a 69 7500 fire tanker truck with 14k mi & 1200hrs. The engine is like brand new. I know you guys are a wealth of knowledge on these! I've read a lot of old posts on this subject& am wondering if anything is new? Like is anyone making customflywheels this conversion?? I'm told that all connecting rods are same length ? If that's true I have a305e on stand w/28k could I put that in the 478m or won't it work or not feasible (forgot to mention fire trk is a a479m) was hoping 351m! Does anyone have any thoughts on that swap? Don't want a race truck or enter in tractor pulls!! Just something different that looks stock/ it's plaid valve covers!! Is weight a real issue if I take everything off I can . It is 3/4t. Thanks so much for your input!!! I love these trucks &these enginesm. I forgot to say could I put a 305 crank in that 478?
