Hot LT4 or LS1?
Has anyone messed with those Hot LT4 kits? They're advertising 425+ hp with them, but I'm a little scepticle.
This of course, is leading to the bigger question... I'm currently trying to decide on what engine to put in my 67 camaro project. About 7 years ago I started just buying parts without really doing a lot of research into what would be best. What I ended up with is a 400 small block with a destroke kit from Speed-o-Motive to make it into a 377 (none of this is put together yet keep in mind), as well as a custom ground cam that matched the TPIS X cam (it was cheaper to have one custom ground then buy it from TPIS *L*). A set of Sportsman II 200CC heads (yeah.. I know, it was all I could afford at the time) and a plan to buy the miniram intake from TPIS that looks like the LT1's intake.
So, keeping in mind that I've got all these parts... I really love the LT1 motors.. and am kind of thinking of getting one to convert to an LT4... or I'd really like to have an LS1 as well. The LS1's seem easy to get to make a lot of HP, but getting a used one seems like a bit of an expensive pain in the butt. The LT1's are easier / cheaper to be had, but I'm curious just how easy it is to get them making some of the big numbers the LS's are posting these days.
In everyone's opinion... whats my best move? Keep what I've got, but obviously ditch the heads and get some sort of fuel injection setup ( a must for my project), or toss it all in favor of an LT / LS motor?
My goal with this car is to have an awesome pro touring car that I can drive in traffic just as easily as I could take it to the track and have a lot of fun in. It's getting some sort of suspension treatment, definitely a six speed.. and who know's what else. My horsepower goals are somewhere in the 500's... or enough to get confused looks from the handful of new 'vette owners in the neighborhood.
Thanks for all the help!
