The engine is beiing build by Ken's Speedshop in Florida USA: 455 bored 0.30 7F6 heads flowed to about 280/310 6.8 BBC h beam rods All pontiac forged krukas (3,25 main 4.28 stroke) Mel. 60 psi oil pump Competition custom grind camshaft Competition retro roller hyd. lifter set Moly pushrods 1.67/16 roller rockers Bgi 220 fuell pump Csi electric waterpump v8-71 roots blower Before the engine was rebuild my car drove on an impco LPG system but i wanted to know if it's possible with the settup for the engine to run it on LPG witH?? 2 impco 425 mixers or something like that and if someon did it already ( probably will but you guys are a bit further with LPG then we're in the Netherlands.) Every information is welcome. Thanks and happy hollidays. Daan Holman The Netherlands

Daan, Great to see someone popping over here from so far away. You may get an answer here, but also try your luck at www.aussiev8.com.au (http://www.aussiev8.com.au) Copy this whole thread and put it in the "Conversions and Rebuilds" section. There is some very knowledgable people with LPG over there! -Kane

hmm 4 b2 convetors and 2 425 mixers, I recon ud be running out of gas when she comes on boost.

Try to obtain the OHG 450 mixers instead if you want to go the mixer route. You can modify the metering jets on them too to get more out of em. What I would recommend though is liquid injection. Because your in Europe it should be easier to find someone who knows about it. I buy eurogas vapour injection which is made in the netherlands. My advice would be to go for liquid injection running any good engine management to control it. Icom in italy build a good injection system but there are companies all over Europe playing with it. Liquid injection will yeild greater power outputs too as the cooling of the intake charge as the LPG is injected can act as a intercooler on boosted engines. Its the way to go for sure, its just gonna need someone highly knowlegable in engine manegment mapping and LPG.
