So he claims to have bored an engine that stock makes 350 crank HP to be 6.2L and make over 600 to the wheels? Naturally aspirated? who else wants to call BS I am pretty sure that engine stock was a 10:1 or close to that compression. Also the 6.2L corvette engines generally dump somewhere around 450 to 500 HP at the crank.Have a local idiot from a car show with a 02 vette talking mess about my car. He claims to have had bored out his ls1 5.7 to a 383 with port/polished heads and long tubes headers. He does have long tubes from what I can see, but his car does not sound cammed at all and he couldn't answer me when I ask who tuned it. He claims it's making 600+rwhp all motor and that he bumped the compression ratio to 11:1 when they rebuilt the motor. His car is convertible with stock wheels/tires, 0 suspension modifications and not even so much as a cold air intake... Claims it runs 10s this way. I want to race him to either shut him up completely or prove I can keep up with his 600hp monster.
I have on my 12 gt:
PTM jlt intake
Jon Lund tunes
JBA after cat h-pipe
Sr short shifter
Barton 2 post bracket
Ford racing LCA's
19" 13 gt500 replicas on nitto invos
I have a 01 lightning pushing 478rwhp/566tq (best 1/4 of 11.01 at 124mph) and butt dyno in the mustang tells me they are comparable in speed once the mustangs rpms get up there. Think I have a chance?
just saying...Dyno sheet or it isn't true.
Like to add, the only way corvettes are making over 600hp at the crank is by being supercharged...
