The 68600's are shorties are they not?

I want to know what long tubes to use.

i have the vortec ones here but they have many many cracks.

I want to run long tube headers but have no idea which ones will fit...

I'm dropping a carbed 99 Vortec 350 into my 95 Safari van but i need to know what headers will fit?

I know on the older tbi engines you could use hedman headers but will they fit and work on the vortec heads?

If so what are the Hedman numbers?

Thanks, Gordon

This vortec motor has CPI SI i believe ( 1 injector and 8 poppets).

The only issue is the obd 1 to obd 2 issues without ripping the entire vans wiring harness apart.

Not even sure if this is do-able due to one being obd 1 and the other being obd 2. I have a 99 vortec 5.7 here and a 95 safari (cpi)... anyone know of a way to get the 95 van to run the 99 engine? The wiring harnesses are gonna be way different as are the ecu plugs. I know they sell a vortec tbi int...

Yup that silvery white metallic looking paint.

The last quote i got with me doing all the bodywork and having it primed and ready for paint was $4200 :-k

It's gonna get a repaint -- Chevy Pearl White. Same as the Escalades paint color.

Should look pretty sweet when its done and it'll haul ass.

I wanna add air bags to it eventually and be able to drag frame at some point.

Figured as much but i wanted to be sure. Done 7 V8 swaps so far but this is my first real "vortec" swap.... ooooohhh. LOL Being as i hate wiring i prefer to just buy an entire harness and plug it in. I got a buddy whos gonna "custom" program the ecu for me taking out the rev limi...

Ok so its that time of year again for me to do another V8 swap :bounce: This time the candidate is a 1998 Astro Van... fully loaded of course lol. Anyhow it has a vortec 4.3 in it... i wanna swap it out for a 1999 Vortec 350 i just happen to have here. Now as far as i know all i need is an ECU and e...

How would you turn down the pressure on a factory regulator?

What can cause a lag i guess at WOT?

When i hold it to the floor at highway speeds it's almost like it's not getting enough fuel but the pressure is steady at 10.5 psi... at idle it's 13psi.

no emmisions here ( cat went bye bye a long time ago..lol).

I do know there is a vac line off the canister on the drivers side that says "to intake" i beleive.

Just need to buy a few T's for all these vac lines.

So you could remove the chip and have it reprogrammed for better performance and higher shift points? Does that chip also control transmission line pressure? I'm really tempted to rip this POS 4l60e out and toss the 700r4 trans i have here into it. The 4l60e just seems so.... soft. Soft launches, so...

Anyone know if this engine / trans (1995 obd 1.5?) can be tuned using the ALDL method?

My shift points are crap... shifts at 4000rpm at WOT.

sooo... putting my cpi pump back in should net more hp?
