Any idea what a cast iron 4bbl FE intake with quadrajet style induction would have come from (small primary, big secondary)?

thanks

Folks

Needing some help here, I used to have a login over at fordfe.com and lost my login info. I am having a hell of a time getting my password reset, as well as setting up a new user id.

If anyone has any clues as to how I can get access over there please let me know. I really like that site, have been on it for a long time but the format sux. This format works much better.

Thanks
Howard

Have a new project for my 66 f100, I built and installed a 390 in it this time last year, specs:

.020 over 390 w/2bbl pistons
D2te heads, nothing special done to them
Crane Cam 343941 Advertised Duration 272/284, Lift .533/.563
stock valvetrain
Duraspark dist w/MSD 6A
Edelbrock streetmaster, stock no porting
Holley 750Vac w/1in open spacer
Truck headers
C6 w/stock converter
3.70 rear gears runs around 3k rpm @70mph

Truck runs good on the highway, seems kinda mushy down low,
Ended up with hairline cracks near the freeze plugs that are now leaking, so I have decided to clean up a short block I had in the shop, drop in a 428 crank ive had for 20 years and make a ~418 out of it.

Replacement engine:
.040 over block with silvolite 1139 pistons
Its cleaned magged and ready to go, I believe the 1139 pistons will work fine with the 428 crank.  Question is, what can i expect with swapping in the 428 crank with the same cam and intake? Would I gain anything by installing a performer in place of the streetmaster? Do I need to get a higher stall converter (2200-2500?)

Thanks
