in my conversion i have a 94 lt1, it has alum heads, stg 1 port, lt4 cam, 1.6 rrs and train, msd6a and coil, ported maf, cai, 160 stat, lt4 knock, afpr, 52mm tb and airfoil. rev limiter is set at 6200, shift lite at 6000.

id like to get more power, who doesnt?

im thinking of changing to a lt4 hot cam and some shorty headers (hookers?).

the big question is the fuel injector size, i found some ford m9593b302 30# for $229. a set, will these "bolt" right in and are they a good size for a hot lt4 cam?

and what do you think of the hooker shortys, im limited on space and i was going to try 2 right side headers to fit, right now i have 2 right side stock lt1 exhaust manifolds and they DONT flow for **** !

whats your thoughts? grumpy?

thanks, don

Im useing 30#lb injectors in my 383 roller engine and they work much better than the 24 lb injectors that cam in the car,the ECU controls the pulse width so yes go for it!heres how to figure the correct size for your engine.

get out your digital volt meter , set it to ohms and test accross the two electrical contacts on the injector it should read between 14-17 ohms if it does you can use the injectors. if it reads substantually higher or lower your probably not going to be able to use them (below 12 or above 20 ohms)

call and ask! but yes in most cases they fit and work fine,(use the digital meter to determine what type injectors you have,they do not work if the high impeadance are swapped for low impeadance styles) btw the ford injectors are just BOSCH STYLE INJECTORS

has these

High impedance injectors (14-16 ohms) are found on most production vehicles. We have found high impedance injectors, that are available on a special order basis, that flow over 50 lbs per hour. Low impedance injectors (2-6 ohms) are typically found in racing and require a different computer such as a Motec.We spend a lot of phone time trying to help customers who have been talked into large injectors. Call us first!
