I've been checking out your build - since you cut the log off are you also going to port the heads? What are your plans for exhaust -are you going to fabricate a header to go with the intake?

I have ported the head and a turbo manifold has already been made.

Another Forced Induction fan very interested in what you find you can share ...

The Holley 2300 (7448?) mod' carb looks good, ,with the Supercharged 250 Maverick, I need an extension on the fuel bowl vent into charge pipe @ 4". The engine would build boost and then lose power cyclically without the extension, . I simply bent a brake line that fit (3/8' ?) replacing the short original vertical vent . I did have to cut down the vent tower a little to fit bent tube under the hat.

Crankcase venting under boost is a concern, currently 250/SC uses two breathers from VC and one vent/breather from mechanical fuel pump blockoff plate port, i plan on joining them into a catch can setup.

What setup are you using for fuel supply and boost reference?


.

first version used draw-through turbo with big quadrajet sticking thru hood with GT scoop raised way up. Ran pretty good but blew piston lands off at @ 15 pounds of boost .

 
:beer: Nice work on the head chop and intake what pistions are you using in your build? Good luck (y) :nod:

well for fuel supply i went for a 45 psi eletric fuel pump fueling an ebay turbo fuel pressure regulator. and for pistons i have in there are just oem. hoping they wont melt under the 15psi i hope to put it through. and do you know exactly what caused the engine to blow at 15psi

I used the tired original 250 engine as a fit-test bed for draw-thru turbo (BOP derived), ran pretty good but at boost would start venting blue haze thru VC breathers. As I kept upping the boost I got significantly more power and a lot more blowby. When I reached and sustained @ 15 Lbs of boost it lost power and emitted a thick blue haze. Upon teardown, I found two pistons with bottom sealing ring lands cracked off. Current Vortech V2 supercharged 250 is freshened, ARP head bolts, better vented, still OEM pistons at @ 8.7:1 SCR and uses a XSTurbo blow off valve on charge pipe 'washered' to @ 7-10 lbs boost. Still shopping for affordable forged pistons before upping boost.

Similar fuel setup with electric pump at tank and Aeromotive regulator boost referenced to carb hat. PITA was adding 3/8 return from regulator back into tank. I added input port to the tank filler pipe in the trunk.

have fun

If you ever find forged pistons tell me haha. Also if you ran a intercooler you could have survived that 15psi and prevented that detonation. That's why I'm hoping that my car can survive 15psi
