Benifit of EL block over EA/ED
Im going to perfrom some performance mods to my car, and with 235000km on the clock i dont wanna put my block/bottom end under a heap of stress on to have it break and have to pull the engine out.
Stage 3/DEV 4/5 equivelent camshaft for LPG performance
Head work: clean up the bowl and increase compression to 10.5 or 11:1 for straight LPG application.
If i run a compression test on my 3.9 block and it returns all good compressions, would i have any benifit using an EL block and head, rather than using my current block and a new worked EL head? If i can avoid removing block it would be excelent. :)
Seeing that the EA engine has 8.8:1 compression stock, and the EF? have arround 9/9.5:1 i can only assume that the compression was made through head work. Or was this done by the factory decking the block? Can a EF/L head be machined to achieve 10.5 + compression on an EA block, or would the block need to be decked, and thus have to remove the engine.
Any help would be appreciated.
Also, Bass_crasy, you have worked EA head on your engine, what compression did you manage, and how much did your head work cost?
Ive been described as a vault of usless random knowledge.
Ill take it as a complement i think.............
