I have a 71 240Z that I have owned since 1990. 3.90 R200. Engine is F54 blk , flat top pistons, N42 head. Supposed to be around 10.5 cr, head studs and Schnieder 260-70f cam. Have good set of SUs, but figure I need more air to run this baby. Don't really want the headaches of triple webers as I don't like tuning all the time, don't know about 390 Holley either. Just want a reliable setup to play a little with , but be able to take on 1000 mile cruise if desired. I'm looking for suggestions, Anyone running a similar setup and engine. Reliability is number 1. Am considering an efi setup, which one ? Got my first Z, a 76 280 in 1980, My track car is an 86 300zx with lowered suspension, poly bushings, adjustable rear camber mods and 3.7 LS diff. Have aluminum LS 5.3, but waiting for TK600 because of $$$ lolol, aren't we all. Am almost 61 yrs old and have found that "not fast enough 20 yrs ago is NOW fast enough. Can't decide on the 240z fueling method. Will SUs be enough for this engine or? Thanks.
