These are for a mild SD-EFI 1990 F150 302. Summit carry two brands - Ford Motorsports (which are clearly stated - must be used with modified MAF-EFI) & the Venom brand.
Are the venom brand o.k.?
Accel also offer them but they seem pricey.
Need to buy new injectors anyway, and just want to ensure I squeeze every last ounce of efficiency out of this engine.
I don't see why the FMS 19lb/hr injectors won't work. I think that comment is to make sure people know that maf vehicles must have an air meter calibrated for the injectors. As long as they have the same resistances as stock injectors, there shouldn't be any trouble running them.
I sent a friend to www.cruzinperformance.com, he got a matched flow set of injectors for a 89 Dodge van, 318 engine. It never ran as good as it does now.
Go on Google and type in, JetorRate. Use the one , Electronic Fuel Injector Tester By Bowling and Grippo. They have plans for a electronic pulser to clean and flow test your own injectors. I'm in the process of building one myself. My $.02. Carl. ...............................o&o>............... ............................
The Motorsport(FRPP) 19lbs injectors will work fine when replacing 19lb injectors. The 24lb injectors need a modified MAF and ECM to have the correct pulse width.
I found a good source for injectors today, outright and cheap.They go by manufacture, primary casting number and secondary number as well as flow tested and group matched. www.injector4u.com. $34.99 x 8 is alot better than $189 x 8 for my 4.6 litre Rover, ya think! I'll use them when I build my MPI system for the 68 F-250 with 481 CI FE engine. Hope this helps, Carl. ...................o&o>......................
