Retro-tek fuel injection system for street
 

Has anyone had experience with the Retro-tek fuel injection system? It looks like a Demon carb, but is a 750cfm EFI. I am considering it for a street 383 SBC with 180 AFR street heads 68CC and a Motown single plane intake. Any idea what cam these might need as far as LSA? This will be for street use in a 57 Chevy with 700R4 and Ford 9", 3.50 posi. Thanks. Mep
