5.9 Magnum block vs 360 LA block....

If you’re not married to LA heads might want to consider all magnum solution. The 402 I have came with magnum r/t heads a 108 cl cam, around .510 lift and 234 ish duration and it runs good and pulls hard, sounds great too. I like oil though pushrods and future upgrades like a set of Harland rockers are half the price of LA versions. I like 10 bolt valve covers - no leaks there too
