EFI-to-Carb conversion Reply #3 – July 27, 2009, 12:43:53 PM IMO, if you plan on staying with that stock cam, that 750 dp might be a tad too much. A 600 cfm carb would seem like a better choice, especially since you using a "small port" E3 4 bbl intake.I am doing a conversion right now using a 88 H.O. Longblock and a E3 GT 4 bbl intake, shorty tubular headers, stock E7 H.O. heads and a stock H.O. cam.It should make around 215-220 flywheel h.p.Might want to use a lokar t.v. cable. Quote Selected

EFI-to-Carb conversion Reply #5 – July 27, 2009, 06:28:55 PM Why the carb conversion? EFI is 1,000,000 times better :D Quote Selected
EFI-to-Carb conversion Reply #6 – July 28, 2009, 03:11:28 AM Yes, I'm planning to replace cam some later.And may be heads. But it's too expensive to ship the heads to my place(Also I planned to use some supercharger setup.That's because I've chosen 750CFM carb.I have Eaton M90 from FI SC.May be I can use it with carb after some hard works...P.S. Sorry for bad english) Quote Selected

EFI-to-Carb conversion Reply #8 – July 29, 2009, 04:36:59 PM The EFI stuff has much better driveability than a carb will. I thought you still had all the EFI stuff on the car but since it's all gone you can go either way. If it was me I would run an EFI set up. Quote Selected
