Unfortunately, the adapters are exactly what I need, but in my rush to over-complicate things, I looked right past them and dove head first into a Typhoon. By the time I came up for air, I realized all of the uppers are back ordered for months.

 

You probably made the right decision, adapting the 302 upper to a crap 351w lower would be my last choice.

It's great some folks are running a stroker on stock tune, but some run lean, for whatever reason, a wide band/ display should be added to the budget for assurance.

Gt40s off a mustang gt or explorer, even lightning (same thing), would be better than the e7 or e5s, depending on which truck engine you have, don't expect a miracle. The heads will crutch how much rpm you can get out of the engine but if your using it mainly sub 3k rpm for daily driving or off reading, won't be the end of the world, be torquey as a hell, just expect to eventually replace the heads...and cam...and stall...and....eventually wish you would have saved longer, tripled the budget, and built what you really wanted, the right way, the first time.
Add gears, tighten up the transmission....will make a difference....save another big pile of cash, build a 408, with the works, decide on SD or mass air, apply appropriate tuning software (even mass air needs to be tuned), then melt all four tires and be happy, that's my opinion.

 

You don't adapt the upper to a lower, the adapters are for the lower to the heads.

 

There used to be adapters for upper to lower, went over like a lead ballon.

Intake to head adapters don't usually come up unless someone's trying to stick a roots blower on a 351w...or some unique 302 intake on a 351w.

Seems there's potential fitment issues at times, with the adapters, lower to head.

As with the ebay intakes, still some alignment issues at times but my money would still go to the ebay knockoff.

 

I'm not a fan of adapters in general, but any alignment issues can be fixed easily with a little attention. The extra surface area to seal inherently sucks, but it's a great ooption for the price tag.

 

Price Motorsport has the adapters that you maybe referring to. If the link doesn't take you to the exact page, their adapter part number is AP-01. I've been contemplating getting this set to use on the 5.8 that i will swap into my truck. It currently has a 5.0 in it now.

OP, hope you're okay if I ask this question to some of our extremely knowledgeable members here.

Would using this adapter and the 5.0 truck upper and lower intake which I already have, be a good choice? 5.8 GT40 lowers are hard to come by and costly, plus I would need an upper, TB, etc. to make it all work.

 

1200$ budget? I gotz the solution. Get a replacement engine for 300ish dollars and spend the rest on a wet NOS kit for that thing and LET IT EAT! The extra engine is for when you shove 350 shot of NOS in it trying to get to the other end of the mud hole.

 

Yes, the 5.0 truck intake is a well designed piece for flow.

 

I ran across this gem in the Bronco forum recently:



5.8L marine lower intake. Notice the port spacing....

Might be a worthwhile adventure to find one so you do not have to fiddle with the adapter route.

I found a 393 kit for 700-800bucks. Will probably try to get a cam from the machineshop. This won't be my last build eventually I will be buying a carb truck to make a monster out of (spotted a 75 with a 460 for 1800 and a 86 with carbed 351 for 1600)I just want a peppy daily driver I can run hard on the occasion, take for a spin through mud/gravel and go back to kicking a mustangs a$$.
Previous truck was short lived but wicked fun. Built 302 with 373s (I think) stock tires. Not 100% sure what was done to it I got it that way and it would fly. My current truck tops out around 95ish takes a year to get there and stops in its tracks when it reaches there. (Using GPS speedo)
If I have to run a tune what's the average price?

 

I too ran across that a while ago looking for reasonable priced 5.8 lower... ()
But how much does that monster weigh?

I have a Explorer upper/lower & have been leaning toward the Price adapters the only real snag I see is trying to adapt linkage.

If something else presents its self, the GT-40 goes to my Mustang.

 

What injectors did you use? I'm starting to gather a parts list. Have the rotating assembly picked out, bearings are chosen, quoted a price for machine shop labor.
Looking at injectors, chip, and that's it I think. I'm gonna go to mustang heads or keep stock atleast for a while. Gears are already mine just have to pull them out of the donor truck.

 

Me? I'll use the 4 hole stockers that were on my 5.8 that I rehabilitated not too long ago whatever manifold selected. No reason to increase them.

 

Surely one of you guys could use the Typhoon intake(upper and lower) that I have for sale...

 

I was under the impression the stock injectors struggled for the stock motor let alone adding more displacement. I'm looking at a jet chip to go along with this & having it tuned (The shops near me don't seem to have a clue so I'm still hunting)

I don't see a lot in the way of tuning a SD system. It IS possible isn't it (Edit:To get a GOOD tune)? Is it difficult or do most feel its not worth the money?
