A '70 Jav with a Factory 390 is pretty good even when compared against a worked small / big block GM. You didn't say what the car would see for usage - street driver - weekend warrior - track only. -->B. Cruising and playing a few times a month. A pair of alum. Edelbrock would give you another point on compression - you could Turbo the engine with a great controller system, allowing you to run the car on 9 to 1 compression around town, take the car on vacations etc. - and still be able to spin the controller for 'engagement' power. -->Tell me more... Superchargers vs Turbo - the gap on 'right now' power has narrowed - the right Turbo will spin up 'right now' and won't be pushing vibration into your crank bearings via the belt, nor be stuffing heated intake charge onto the pistons. -->But turbo's can't match the sexy whine of a supercharger nor the instant RPM. --Rap-- A Turbo 390 would put more power to most any street tires than you can get to hook up and still street the car. After 500HP - it's a track car - mileage will slaughter your pocket moths. -->I'm looking for another 100 more... a 10sec car is streetable... 9's - you better carry more than spare spark plugs... A tank of gas per outting is fine a couple times a month. Octane booster - I can still remember the smell - and the taste... The AMC V8 EFi can be had by having Bulltear.com modify an Edelbrock intake manifold to accept injectors. Use a GM ECm controller - plenty of stand alone harnesses to be had. Visit the www.bulltear.com Forum - you can read firsthand AMC performance engine builds - pretty interesting stuff. -->Thank you Sir... Beyond tackling a total reconstruction - get the car running and plated for the street. Drive it for a season as is & then decide how much more your lookng to get out of it. -->Naw... was going to drop a stroker into my Camaro but that falls under control of the Air Police (emissions). The Javelin is exempt by age. My crotch rocket runs 10sec 1/4's. The Javelin needs to be fun too. Otherwise it's just an old car that the legislative nazi's will want to "recycle". Too many 'Hyper Builds' end up sitting since they're too much to be street driven for enjoyment - and wind up being sold. -->To much power is almost enough... Trim for style, power for smile... -------------- next part -------------- An HTML attachment was scrubbed...
