intake for Jay's adapter.

[fe66comet]

I was looking around at fuel injection intakes for my 445 FE stroller and started thinking about flow numbers. The adapter accepts a Cleave land intake but most of the Cleveland stuff is designed around a 350-380 displacement like the Trick Flow. Those intakes handle mostly Clever based engines from 302-400 max, certainly not enough for a 650 plus 445 cid, Fuel injected, stage X headed, hot camshaft monster. I did find another intake for the 4V headed Cleveland and it appears like it has more flow potential but I thought I would run it past you guys. It also definetly passes the cool factor for looks as a plus......Jon

Jon I did my own FI system on a single plane dove manifold back in 97. It's not preety but works. If you are looking for flow numbers, send the unit to Joe Craine and let him do his magic of matching the ports and encreasing the flow. I see no problem with him picking up 10-30 cfm per port.

I strongly disagree with the 4v intakes not being able to support a 445 FE. It's not about cubic inches, but airflow to support a given horsepower. And I'm sure you're aware of the port sizes on a 4v Cleveland. They are big enough to support some pretty big horsepower numbers. Actually way to big for their cubic inches, which is why they often used the step-down plates. Joe could provide better insight, but I believe the head (mainly the exhaust) is still the limiting factor, not the intake or adapter. A good aftermarket head with a good Cleveland intake and port work should support 650-700hp quite easily.

I will have to agree, the Cleveland intake will support enough air to 95% of all FE on the road!

I looked at the gasket here.         http://m.summitracing.com/parts/fel-1228/media
It is huge by comparison to the Ebelbrock stage X from Barry @ Survival. We talked some about it today and he felt it would be a good combo. I guess the next question is for Jay. Will the 2.65/1.88 gasket be OK with the adaptor? My heads are 1.2/2.1 so there is some squeezing going on there. I may go to a slightly larger intake port size for a good transition. I am thinking about an 1/8 inch all around. I guess I will make that decision when I get there. Anyhow being fuel injected and dialing my throttle body properly I think it should work good if I plan ahead. I have already ate some money for not having foist ( anyone interested in a Dual Quad air gap Edelbrock intake with two E85 750 performer EPS thunder carburetors ?) Whoops ouch! Guess I should have checked the availability of E85 first.

Jon, that gasket should work fine with the adapter.  In fact, the ports in that gasket are even a little bigger than the standard 351C 4V ports, and also bigger than the ports in my adapter.  I'd suggest you get the adapter and the intake manifold combination bolted together, and do your port matching at that point.  You probably shouldn't go all the way out to the gasket when you port match; just line the ports up between the intake and the adapter.  Same with the adapter to the heads; you will need to port match the adapter just a little to get it to match up with the head ports.

Hope that helps - Jay

Sounds good I think the Spyder FI intake with the proper size throttle body should work well. I am thinking about a 110mm round would do it. I am gonna need to get a better idea of demand first.......Jon

Jay, I'm wondering if you have ever ran a eldebrock UR-19 prostock tunnel ram on one of your adapters on the dyno or other wise ? How did it compare to the regular weiand tunnel ram. ?

[BH107]

The pictures SBF intake looks just like an Edelbrock Victor Jr with an elbow bolted on, something that's been done on 5.0L based engines for a long time... Not sure what they use for the Cleveland, but it's nothing new...

Unfortunately I don't have one of those intakes to run.  I've got the Weiand tunnel ram and the Offy tunnel ram (currently loaned to me by Bob Sprowl), but that's it for tunnel rams.

There was a very nice one on eBay , it suddenly sold today though. I had been watching it for a while, you know just watching and wishing lol. Wonder if someone here picked it up. Would be interesting to see how it preformed.

My thoughts when I grabbed my magnesium Kinsler 351C sprint car injectors was that the airflow of a 410 Cleveland at 9K+ might be close to the airflow of an FE at around 7K- IIRC the Kinslers are 2-5/8 bore. If you never heard a good dirt Cleveland, you missed out- really stood out in the sea of Chebbies. A friend of mine bought a couple Jack Roush engines for his dirt car in the late 80's, couple serious screechers- and the Chebbie guys cried like whipped puppies. When a guy runs a full second faster on a 3/8 mile dirt track, you could call that a significant margin lol...

There was a guy here that streetraced a 69 Mustang with
a Rumored ex prostock Cleveland Engine. with tunelram,
exhaustport plates and the whole shebang and a fourspeed
Woow the sound of that Engine you Heard it for miles and miles
on summer nights
The meanest Engine sound i ever Heard He beat so many
Bigblock chebies  so streetracing died out around
here for several years
 He had an Edelbrock UR 19 on that engine

The UR-19 was a very popular pro stock tunnel ram for Cleveland's with iron heads and raised plates back in the early to mid 70's. Pinto's and mustang ll' s. I loved those cars.. I wish I would had the $ to pick it up, it was a NOS manifold, never bolted up and had two new Dominators that went with it, all for 1,700.00 . hell that was a steal cause the two carbs woulda cost that much. I was hoping someone her picked it up, I know you guys think I crazy but I woulda cut the bottom out of that thing and sent it to Jay and let him run it up on his dyno just to see how well the old school would do. I'd love to do that with my hybrid cast/fabbed intake I made for me. I'll haveta Seattle for letting a bowtie guy run up my combo though.. I'd love for a good trusted and experienced dyno guy that is well familiar with FE 's run it up and help with the tune. I need somewhere on the east coast from North Carolina up to MD area.. Been thinking about once I get it all done and together, about taking the car up to booze brother's and let Brian help me out and test a few things on there chassis's dyno cause that's really what I need. Engine dynos are awesome but being I'm all out racing I tend to think the chassis dyno is gonna be better suited or my needs with helping setting with a good close ballpark tune and setup.

By the way if anyone is intrested in a set of 351 C cut heads and Roush exhaust plates that haven't been ground or anything, let me know, a good friend has some, hes an old timer and doesn't do much internet but I could get you his contact. And show him how to text Picts.
