    won't be long now. i'm excited to hear how it does. i don't think you'll ever get the 2 injectors to work right. they would have to be exactly perfect to work. reminds me of the tri-power carbs. my dad said they were amazing, but getting them to work right was rough.

          most shops don't care what tires you have or what exhaust you have. I'm sure they've had cars in there much louder then yours will be.

              .... just spoke w/Jay over there, who sounds like one hell of a nice guy! Open exhaust is fine, but it's no longer $60.00, it's a whopping $75.00. He stated to just give him a heads up beforehand of course. I'll be bringing the video camera, cuz I'm getting my blown GTA dynoed the very same day.

                nice rob gonna be a fun day

                except i had an accident at work,i just got out of the hospital and from seeing an eye doctor who had to remove pieces of a carbide cutter and metal chips out of my eye.

                so im putting this on hold for a minimum of 1-2 weeks depending on how long it takes my eye to heal before i finish up the car
                let alone i have to waer an eye patch for the next week over my left eye

                  Boosting and porting dosn't make a whole lot of sense. All that presure will make up for any shortcomings in the intake track. The valve ihead tself will limit airflow at 28psi. Maybe I missed somthing in this post...

                    porting does infact help on a boosted motor,im in to much pain right now to try and explain it though.
                    well heres something for u to think about
                    a stock grand national head flows 127 cfm on the intake side and they have the same size int and ex valve.

                    with the right combo and stock untouched heads these cars can break 10.90 but thats about the limit. now take the same heads and port them witht he same sized valves and those heads will run into the 9's


                    i dont know how many of u guys have ever seen a gn cyl head but they are far worse design and flow less then the 60* rwd iron heads


                    on a side note

                    it figures that i would get hurt working on a set of 90* v6 heads lmfao

                            i have saftey glasses on from the time i walk in the door of the shop till i leave to go home.

                            while its very hard to get something in ur eye with them on its still possible,from now on i will be using goggles instead of glasses since they offer better protection.

                            i also made things worse when u get something in ur eye ur first instaintct is to rub ur eye,which u shouldnt do. well i did it and ended up pushing the pieces of metal deeper into my eye.

                            wish i could take a picture of my eye for u guys so u could see how serious it really is.
                            hopefully those of u who do read this will always were ur saftey glasses and whatnot this is somethign u really do not want to have to go threw.
                            ive had broken bones and cut fingers on the bandsaw etc that havent hurt as bad as this does

                              This is pure truth! Goggles are ftmfw! As much as I hate the comfort of them, it's the least to put up with rather than a shrapnel in the eye.
                              I'd rather look like a dork than an idiot with no eye sight.
