Hi Guys,
After the serve bashing I got from my ideas to improve my car "Project Tire Fryer" and after buying some XXX302 heads/cam/carb and importing to NZ I have sold all that stuff in NZ now and starting again. So I do listen!
I looked the magnum head swap idea but that was going to cost a lot for me to change over approx $3000NZD once you take shipping, heads, rockers, push rods, head bolts. (Hughes has a kit for it that has all the parts to do it)
So lets start fresh I now have a 770 cfm holley street avenger carb, air gap intake, a set of 360 heads being pocket ported, port matched 2.02 valves fitted, 30 degree valve job, deshroud valves a little, some blending and shaved 40 - 45 thou to bring compression up, adjustable roller rockers, .028 thin head gasket along with a 2500 stall converter and a trans rebuild kit to handle 450hp with a stage 1 shift kit, not that I think I am going to make 450hp.
I see every 360 dyno flog they run a 750cfm carb or one of those big thermoquads. The airgap has got the big 360 ports where the performer has small 318 ports (performer seems to be not much better than the iron 4bbl intake)
The head porter guy says he should be able to get over 200+ cfm out of the heads upto about .450/.500 lift so that will be good.
Taking 40 - 45 thou off the heads should see me at 62/63cc won't know for sure until the heads have been CC'ed this should bring me into the low to mid 9s for comp.
The .028 heads gasket is better than the .039 - .048 felpros this will also help gain some compression.
I also now have a trans kick down cable setup to get rid of the linkages. Have a trans cooler to go in as well.
So once all this is done and don't shoot me down for using a 3.21:1 rear end ratio, gas has gone up here we are at $12.39NZD per gallon! So don't you guys in the USA ever complain about gas prices!
This is going to take me a while to get all this sorted, the trans parts are still on their way from USA and the heads are still at the shop getting worked on. Once the heads are done they will out flow stock X and J heads.
So this should be more inline with what your guys have told me in the past, lots of flow and good comp make good power!
Thanks
Bruce
