Another newbie...be gentle! Greetings fellow gearheads!
I am delving into the wonderful world of LSx technology, coming from the good 'ol gen 1 SBC engines. My "project" is a 1984 Corvette...yes still with the dreaded crossfire injection system. I have about tinkered this system to death...so time to move on!
I'm not doing anything really aggressive...I just want something with significant get-up-and-go, decent highway mileage as my son and I do a lot of road-tripping. I'm not interested in drag racing, or the best 0-60 times...yada yada.
My "plan" is based on a LM7 (I think?) 5.3L block out of a truck (hey I got a complete engine and 4l60E for 200 bucks, heheh )...punch it out to 5.7L, stock LS1 or LS6 pistons. I already have a LS1 intake and (returnless) fuel rails, LS6 injectors, 75mm throttle body (cable), MAF and C5 intake ducting. I'm planning to use the truck heads but of course open the valves up to 2" (and 1.55 as I recall...whatever the LS1 exhaust valve size is). This according to my calculations will yield a static compression ratio of about 10.8:1.
I'm not entirely sure exactly which cam I will end up going with...that's kindof an ongoing research project. I will definitely be more aggressive than a stock LS1 or even LS6 cam, but not nearly as ridiculous as what I have in the old crossfire engine now (Edelbrock 2204)...a little too lumpety lump!
Well probably enough babbling for now. Look forward to learning some cool new stuff...and who knows might even be able to provide something! (hey stranger things have happened! ).
