I have a 4100 and want to change it out, can I put a 350 or will i have to put 307 in it. I want to change it out for a better engine what should I change it to and what mods will have to be done. If it were you what would you do?
if it is a fuel injected 4100 u could put a 350 fuel injection in it from what i was told the harness is the same it should bolt right in also matters what kind of trans you got if its universal you can put it on . check on the info im sure you can bolt on the 350 if its fuel injected.
check out this site. This is with an eldorado, but it's still the HT4100 he's swapping out.
And if I had the money, I'd go for the bigger motor... I think that the rear wheel drive tranny could handle the torque.
