    Lets see if I can help...

     



    I have build several 327 mills... Here are a few examples of what I have done... keep in mind that I am usually building on a budget, looking to get the best bang for the buck...

    First off, I think a good place to begin is to look at the specs of the L79 motors that were offered by the factory and were rated at 350 hp...

    I would probably step down on the compression of the L79 from 11.0:1 down to a flat top piston around 10.25:1 to keep it on pump gas and allow you to mill the heads if needed... You will probably want to bore the engine which will give you a few more cubic inches while giving you a new clean cylinder surface to work with... You did'nt mention what size valves your heads had, but I would definately consider going to 2.02/1.60.. The last set of feulee heads I had built for a 327 I went with 2.05/160... As far as a good street hydraulic camshaft I usually go with about a 210/455 cam which you will need to run with a stall-converter for best results... A set of anti-pumpup lifters and stamped steel roller-tipped rockers should work just fine. I have run several options for carberation, the photo below shows a stock chevrolet 2x4 low rise intake from a 62 Vette with twin Carter AFBs... I also have a 327 which uses a Torker intake with a Holley 750...

    O.K... with that said here is where you can really make a difference if you are looking to have a quick street car... Tranny and gears... Understanding that there is a difference between having a quick car and a fast car, with a 327 you can definately do quick... To make that turbo 350 tranny perform you are going to need a 1000-1500 stall converter to get your power to the ground without bogging on the low end, a shift kit will also help but I usually opt to have to have a transmission expert built mine so that it shifts hard... A good set of rear-end gears will help too, I like to stick with 3:23-3:55 to keep the car streetable but still quick... I would definatly not go any higher than 4:11 if you want your car to be truely streetable...

    The engine in the photo below is a large jornel late model 327 and was built using the specs above...

    Hope this helps...
