Hi Guys,
Ok where to start, I bought a LA 360 from the USA to NZ, its come with a holley 870CFM street avenger, I have a holley 650 vac secondary and I have a new 600 Holley arriving next week. I originally bought the holley 600 for my 318 but have gone 360 now. Anyway I get onto summit website it says the 600 should be fine up to 6800rpm with a VE of 85%.

My thoughts are the 600 will give low end performance with good air speed, the 870 will is pretty big and might bog but in their day Chrysler put some pretty big spread bore thermoquads on 360s, has anyone ran a 600 on a mild 360 or should I be thinking the 870? or is the 650 where its at?
I would like to run the 600 if I can get away with it, for 2 reasons its new and I know I will have many miles with no problems, my 650 will need a rebuild, it leaks on the fuel tube and the 870 is an unknown been told it works fine.
360 going in the doba
Thanks
Bruce
