Opted on building the '84 z28. Tearing out the 305. Efforting now for a 350 or 400 Small block.

?1 Which aftermarket injection system should I go with? There are many and I don't know the pros/cons.

?2 Which heads for a medium street build up? I think I want to go aluminium...Are the aftermarket better or worse?

Thanks..

I don't know about the "better or worse" aspects of the aluminum heads (that can be very subjective), but I know that the aftermarket aluminums are usually less expensive.

No real help on the distributor, but Mallory has built a decent reputation over a few decades. You might start looking there.

Any particular reason you want to spend the big bucks on an aftermarket injection system? Power-wise, it won't do any better than what you can easily do with the carb already on it (assuming your 305 has the normal CC carb).

Hmmmm, I thought the injection made for a nicer daily driver. Less cold natured, better idle, ect. It doesn't?

305 is history BTW...350 or 400 going back.

It definitely does. Better gas mileage and power in some applications. The toss up is that damn ECM. You will lose your ability to tune it as that is what the computer does. Way more complicated and harder to work on. You will also have sensors galore to worry about later.

i've heard nothing but good things about the holley stealth ram

Hmm, again. I was thinking several of the aftermarket injection systems were "tuneable" and adjustable thru using a laptop..right/wrong?

Oh yeah, it's just whether or not you are into that. I was talking more of a "mechanical" tuning aspect. If you are good with computer tuning and what not, GO FOR IT! That stealth ram is killer, but quite expensive.

yeah most aftermarket injections are completely tuneable.. otherwise it wouldnt make much sense to sellem unless they were designed specifically for a certian application.. personally i'd love to have a hsr but when it comes down to it i can afford a carb.. hsr is kinda outa my price range..

If yopu can come up with an LT1 or L99 intake, you can have it converted for a distributor and "normal flow" cooling for about $200. That's a pretty reasonable alternative to the HSR, which is basically an LT1 intake clone.

EFI is certainly tunable, as well as the factory HEI system, as long as you have equipment to burn EPROMs and read data from the ECM.

Which aftermarket heads??
