Well I made it to the track last fall with my 6.0 obs rcsb truck ran good went 12.30 at 110 current set up is a stock lq4 with shaved .030 243 heads unported .shonefeid long tubes comp cam 23x /24x .598/604 on 112 edlbrock pro flow xt with 42lb injectors 90mm edelbrock throttle body .4k M&M convertor turbo 400 9in with 3.89 gear and assassin bars 275/60 et street pros .
I am building a new 408 for the truck with goals being to get the truck in the 11.0 to 11.10s NA I am on a pretty tight budjet and would like to keep the intake and heads just get the heads ported talking to Next generation performance out of Oklahoma They have a cnc program getting the 243 flowing in the 340s
Another reason I want to keep the cathedral port intake is I have a nitrous express 90mm plate kit that I want to run. any input ?
