I'm thinking of converting my carb'ed 383 LT1 over to EFI. I'm not very familiar w/ EFI and was wondering what size injectors I should run.

My head flow numbers are as follows:

Intake Exhaust
.200 127 104
.300 190 142
.400 233 180
.500 265 190
.600 269 198

I'm running a CC306 cam w/ 1.6RRs which has 230/244 duration w/ 112 LSA. My compression is 11.7:1. I'm running Hooker LTs w/ a true dual exhaust going to Flowmaster 40s.

I was thinking I might need 36# injectors for this as I'm hoping for around 500HP (crank). Any opinions/advice?

Thanks,
Jason

 

Im hoping for 500+ HP and I ended up going with 36lbers. Your better off having a little too much injector than not enough.
