Well ,the only thing we have done is a cam,and well the intake to run a carb,and we changed the valve springs for the 609 lift on the cam ,the heads are bone stock, its the LQ flat top motor they have LQ9 and LQ4 i have the dome piston motor and went 11.40 all out and i spun a rod cause it was a hight mileage motor and went to the flat top its 10.5 from the factory and no spray,no my friend with a 67 camaro has the same setup with LS2 heads and a 150 shot and runs 9.90 with it and thats through mufflers, he shifts at 7500 rpm thats too much for my blood im at 6500 , lol but for a muscle car ill never go back old school it takes 10 grand to build a 383 to run that ,and im very honest on the setup,and the reason we went new style no one around here in deep south louisiana has these in there cars and his brother is in the auto sales and gets all we need from Copart the auction company, and thats the whole truth ,and every one thinks we have head work and all kinds of stuff and that can look and check but they see the stock heads,
