Sounds great Brandon looking forward for the new numbers..
Did you flycut the pistons? or does the car have built engine?

Thank you for actually putting a set of "good" heads on the car. Especially with that type of cam. Im sick of seeing HCI ls1, and it has damn stock 243's.

Do you have the cam card, can you post it?

 

[dizzygoat]

if i had to guess id say 470hp and 420tq. The gears are going to eat up some power, are you auto or 6spd? All this is speculation, the cam specs say little without the card.

If he has 4.56's with a hc ls1, what about my hc ls1 with 3.27's? How much added hp am I looking at?????

 

[dizzygoat]

well in theory you are not "adding" nor is he "losing" any power due to different gear ratios. The motor will make the same, its the parasitic loss we are talking here.

 

[Demonicbird00]

yeah what numbers from the cam card do you want

im a 6spd w/ a spec twin

i added 28" MT DRs so im going up at least to 4.56s but leaning more towards 4.88s

i dont have good dyno numbers as of right now, we think its running out of fuel above 6k, i upgraded to 42lb inj but the stock fuel pump can push the fuel ( 12yrs old and 131k) lol

flycut pistons
