V6 Performance Parts

Will the stock pump & injectors, on these engines, support a small turbo?

I believe so, from what i read, factory injectors will support 400HP, the pump, i would probably swap out if it was me.

4.3Ls are great engines, my Orange truck had one, and i had done some performance stuff to (Edelbrock Performer TBI Intake, Ultimate TBI Mods, some other minor bolt ons), but they just cant measure upto a V8 without Massive $$$$$

My blue truck also has a 4.3L, seems like its more solid then my 94's old one (Had a rough life) this one gets decent mileage, and even with 3.42's, has lots of jam!

I think you got them switched up or something. I don't think 4.3L injectors are good for 400 hp, maybe 454 injectors are.

I've been having a hard time finding an injector spacer. Where did you get yours?

Another cam company, but I'd still just get a custom grind.

just so others are aware, those are flat tappet cams, and 4.3L's had roller cams earlier then 305/350's, since 1992 i believe.

Pretty sure every GMT400 V6 has a roller cam. Pretty sure they started when fuel injection started on full-size trucks, 1987.

maybe, i figured they might have started with the balance shaft.
