Hey guys,
So I have a 351w roller EFI. I thought I heard years ago that you could use the upper plenum from a 302 on the lower plenum from a truck 302... I'm wondering if anyone has tried the 302 upper on a 351 lower? My car is in winter storage at the moment so I can't measure or swap. I'm also talking about stock EFI intakes.
If nobody has tried this I'll give it a shot in spring time. If someone has tried or has any input by all means post up.
And yes, I'm looking for a cheap intake option for a 351 swap.

Have you seen a 351 truck lower? It's unique.

far right. No other intake will bolt to it

It used to be you could buy an FRPP 351 lower intake (from the Lightning) & bolt on a GT40, Cobra, Or Explorer upper intake onto. Here is a current Ebay link to one being for sale: http://www.ebay.com/itm/351w-Gt40-Lower-Intake-5-8-Mustang-Gt-Lx-Svo-Cobra-Windsor-Sbf-/111595910599 From what I understand, these are not available through Ford anymore.... You might be able shop around some swap meets or check with local enthusiasts for a better deal?

Yes it seems they are much different. One of those lightning lowers with GT upper, throttle body and 24# injectors came up for sale not far from me. 700$ sounded high but may be not too bad. They look pretty slick. But still getting close to the price of a new tfs or edelbrock.
Thanks for the input!

Iirc, the holley upper will bolt to the stock truck lower, but the ports are waaay off. There was a guy on corral who was cnc porting a 351 lower for the holley, dunno what came of, but it's not exactly the best idea when you can probably find a whole used edelbrock 351 victor for less.

Holly upper is modeled after the truck 302 intake...which is the center intake on above pic.

I don't know if the hood clearance will allow, but BC Broncos has a adapter. It allows for the truck 351 lower to be mated to the car 302 upper.

that's a pretty slick adapter... too bad I forgot about this thread. I should check this place out more. I ended up buy a used lightning lower with the tubular cobra upper. Which I find to be a very good looking set-up. It may not flow the most air but if I add some boost it will perform very well.
