Thanks for the excellent advice. I am leaning towards a supercharger for 2 reasons: 1. It will fit 2. It's adjustable and always on and shouldn't require much maintenance....ok thats 4 reasons... John, Do you know "Dave". He built this car. I would like to work on the suspension after I am done with the engine and interior.

Nitrous sounds good. I heard you can get a Nitrous kit that will electronically adjust the timing. Any recomendations for a 75-100 hp nitrous kit for this Holly carb set up? Is there anyone else here in N. Calif? Do you have a page where people talk about their performance (i.e. 1/8 or 1/4 mi. times)? lilredZ

Do I have to run an additional fuel pump? I don't think this block will take more than 500 Hp but I don't necessarilly need more than 500 HP...so many options but I want to beef it up a bit. It runs solid 12.4 ETs with the exhaust (mufflers) on but runs 11.8 without it. I want to be able to run 11.5 or faster with the mufflers on so Nitrous sounds very attractive...I may just do a Nitrous kit with a little more encouragement and some reading... Thanks for the reply, lilredZ

This is a cool group. Do you guys ever meet up? Anyway, I just bought a beautiful (show quality) 1973 240z with a 337" Ford motor. This was built correctly. Ballanced and well engineered. The guy spared no expense. It has a 4.03 bore and 3.3 stroke in a C4 289w block. Its flowing 250 cfm intake with >.5" lift. The estimated HP is 400+. She runs low 12s all day with mufler and 11.8 without at 119 mph. My simple objective is to run 11.5 with muffler/s...so I am guessing a 50-100 Hp boost will do it. The engine has street fuelable 9.2 to1 compression. After reading many warnings about blowing this block I am thinking about going with the 300 cfm flow heads... I don't want to do nitrous...not sure why but... I come from the old school of tuners where N2 was sortof cheating and your tuner should be able to rake any production car. Now with these modern cars this is not so practical but I do need to spank Z06s...and that will require another 50-100 hp to be absolutely sure that the only Z06 that will walk from me has to be a tuned one... Any thoughts are appreciated... Newbie, lilredZ
