i have a1990 ford F250 5.8L windsor motor that was bored and stroked to 408. Still running stock intake and heads, 61 mm BBK throttle body, Converted to mass air, replaced stock injectors using 24# now.

I have 339 ftlbs of torque but only 177 hp. When I start the engine it revs high then settles down then runs rough, stalls and dies. It seems after its driven for a while it will stay running when stopped at lights. although sometimes it will stall out.

Anyone have any comments or suggestions.
This is really turning into a nightmare. thanks in advance.

check your iac (idle air control) and for vacuum leaks.

Definitely check the IAC. And vacuum leaks.

With a 5.8L, I would go to a 70mm TB.

It's just a SUPER-DUTY Mustang GT Sedan

1997 Crown Victoria P71 SVT *** ex-US Marshall service (the CAR)

STOCK?? I bet it was modified.

13.26 @ 107.24 MPH 1/4 mi w/me, tools, & full tank

I added CAI, NICHE 19 X 8.5 " wheels with 245/45ZR 19 rubbers, and completely rebuilt the front end with poly bushings

.PLANS 2000 engine upgrade, 5.4L stroker, rebuild interior
