ok you guys i drive a 1988 chevy astro van with a 4.3l vortec engine. i know the best thing i could do is change the mortor mounts and drop a 350 in but i dont want to deal with that. i would like to keep the 4.3l and add parts to it.
does any one know what intake manifolds and carbs i could add to give me some extra torque and HP? i know for a fact lots of companys make parts for the 4.3l vortec but my main consern is clearance with my engive cover(remember it is a van).
If you guys got any info or suggestions that would be awsome. let me know whats up fellas.

don't do it, bag it or buy something else...my friend has a bagged astro w/ custom paint, frenched plate, and shaved everything. it looks sweet.

20" with a 2" tire fit the astro with no mods needed. so 22" with a little modification is totaly possible. might need to increase wheel well size a bit but that just cutting and welding.

theres a newer one droped on 20" same wheel demsions as mine.

Well, put a cold air intake on it, exhaust, pulleys, powerchip, shiftkit. That should get you closer.

Well, put a cold air intake on it, exhaust, pulleys, powerchip, shiftkit, headers (if they make them for a van), more aggressive camshaft. That should get you closer.

Later

And the stickers that say stuff like, "When the Vans a Rocking, Don't come a Knocking", and "Don't laugh, your daughter could be in here".

well like i said iam not trying to make it race ready if i was doing that id drop a 350 in, alls i need is a little more horse for the highway. i think iam going to just get some hooker headers and a new cam shaft. should give me everything iam looking for.

and yes it is the same as the s10 4.3 but no room at all to slap a super charger in. but that would be very sic. or maybe somthing like this;

I read a build up in Hot rod magazine of a 4.3.
They explained that the 4.3 is actually a 350 with two cylinders cut off, so the pistons and connecting rods can be swapped with high performance pistons and rods. The heads and the crank are a different story though, there is no known manufacturer of highperformance heads and cranks for a 4.3 so you're left with the other option of porting you're existing heads and getting you're crank balanced. I forget what they did for an intake manifold and cam but I know they managed to get 350 horse out of it reliably off regular gas.
