TOP 5 HP GAIN MODS (poll)

In your case, I think it would be a nice/affordable investment to go with the shorties.

That's exactly where I'd want the gains (low/mid-range-that's also where the spacer and intake seem to help the most). That would help in towing, and that's what I'm more interested in (for the truck, lol). And it just seems like those TBI engines have as good a bottem end as the newer trucks. Now the top end is a whole nuther story, lol.

I'm definetely going to look into the shorties though. That and Edelbrock's Multi-Port fuel injection conversion for the TBI engines. On Horse Power TV, they installed that on Chuck's 93 C1500, and it gained 20 hp at the back tires, and they said it gained a lot of torque and fuel economy. Now the multi-port F/I conversion is pretty pricey (around $1000), so that will come at a much later date, but I would like to get some of the shorty headers.

When trying to get more performance or power the work never stops.

I agree 100%.. Once you do start to feel a difference, that isnt good enough anymore and you want more more more!

But as for the poll.. The way to make power is to get air in and out as fast as possible.. So, first off.. air intake, and exhaust/headers..

regardless of wether or not they giver u the best bang for buck, you still shouldnt do any other mods until they'r addressed..
Slowprocess summed it up pretty nicely..

1)air intake
2)exhaust/headers
3)free mods (egr shave, tbi coolant bypass (proven good for up to 8hp), etc.)
4) Shift kit (and corvette servo if possible) will make your trannyt shift faster and harder.. puts more hp to the ground and makes a world of difference shifting..

5( A good dyno tune.. Never heard of this allen nelson charactrer.. But

I'm not sure, and I could totally be wrong, but i don't think that he can tune a v6...

Worth it though, but I'd never do it again.

Too bad the auto manufacturers don't make it easier to upgrade the engine in the vehicles

No, what I mean is having the v6 and v8's all use the same harness, PCM, etc. That way you could just yank out the v6 and stick in a v8 without trying to figure out how to rewire it, etc., etc.

aahhh yes. Those were the days. I can put a number of engines in my 77 ford f150. I even had room to stand INSIDE the engine bay while mating the block to the tranny!! I dont think that would be the case with these newer trucks. This is my first vehicle that WAS NOT made in the 70's. They sure have come a long way since then.

[profox02]
