I have 3 restored carbs , aluminum manicolg Linkage, fuel lines and more message nme for detailz

I bouvhy it from a guy who did lit of work, focimented everything. Thr cars idles smoothly, always fires right up. But after it warmms up, sith moderate part throttle load, 3.23 rear gear, Th400 tranny . Completely stock base 400 engine

The car is running the stock setup, with original i not switchbinh C to Tripower until the detonation/ pinging is fixed

I used A primitive holley water injectir on a modufied 455 bsck in 1986/87. It worked , but it was poorly controlled . Has anyone used one if the AeM lr Snow performance kitz? i worked out an idea on how how to. Plumb it with tripower. I will add1” spacers to all 3 carbs, and drill and tap each venturi in front and resr carbs ( total 4 nozzles). It should work.. but the injection companirs have nothing to say on using it with Rochester 2GC carbs. So im on my own.

Yes, well i want tripower as i had it 30 years ago and it was a blast. But i did run a primitive Holley water injection on 455w tripower, cam, 9.5 compressionw 1972. 2bbl 400 heads, 2.11/ 1.77valvres. It never ran right( the tripower was in bsd shape). Now i have restorex tripower, stock motor,, 10.5 compression. It pings ehen driving hard. I addrd 4 row desert C cooler, 160 degree thermostat, flrx fan. And still had to retatd timing too avoid detonatoon.

Hi, i intend to replace a quadrajet on a GTO 400 stock engine . Can I expect better performance? Its A 1966 restored tripowrr with aluminum manifold. also. Anyone added water injectin to a stock a stock 400 10.5. Compressionnr Ratiol? Engine has less than 5k since rebuild its numbers matching engine, i dont want to change heads to lower comoreszion. Any ideas?

I am looking to restore my Mint GTO, BUt plan a few chANGES. IM PUTTING A 1966 TRIPOWER on it soon. And possible adding water injection . Anyone have any tips or experience with r tripower or water injection? The plumbing is a huge challenge. I called 3 mzjor wateer injrection sellers, and they seemed stumped, I figured on plugging the injectors ijnto the base plates of front and rear carbs. But the spCING IS TOO Tighrt My next thoufht was to drill ports into the side of the pleneum under the cenetr carb, as close yo the center carbs venturis. But I dont want tik wreck a manifold. I will be using an aluminum trippwer manifold. But I need some expert help. ould thiox approach compromise the mamifold? The guys I spoke too said the injectors must be horizonatl as possible, and cannot connect through anggled fittings. I cant find a nitrouse type plate to mount under the Rochester 2 GCs.. apparently no one makes any,. My last thoiught was to buy 1’ aluminum spacsers ( widely available), and drill 2 port ain each end. carb spacer, and ire it to open when the end carbs go fulll opemn, But This does nt help part trhrottledetlonation occurrrin ng only withce thew. center carb only. I dont wa nt to ch\a nge heads, the en giner has only 5000 miles since rebuild.
