LQ4 build questions I'm about to start building my LQ4 and I have found a couple of compression ratio calculators and I am trying to figure out what set-up would be best for me to run on 93 octane. I was told i want my DCR around 8.7-8.8?
Does anyone know the stock specs for an Lq4?
rod length
stroke
bore is 4" I believe(please correct me if I am wrong)
deck height
piston: dome or dish and how much
Reason I'm asking is that I have a set of P&P'd 243 heads(milled .055 and 57cc combustion chambers) that I originally didn't think would work for this set-up, but i thought I'd ask to make sure.
thanks for any help.

rod length = 6.095"
stroke = 3.622"
bore is 4" I believe(please correct me if I am wrong) = 4.00"
deck height = 9.24"
piston: dome or dish and how much = dish, 4cc (IIRC)
With your 57cc 243, your CR would be at 11.30:1

If by deck height you are referring to piston to deck clearance most people use -.008", and the dish is +7cc. Static compression 11.07:1 w/ stock gaskets and 11.54 w/ .040 cometics.
