How much rear wheel hp I can anticipate ?

Thanks !

O.K,first off love the long rods good idea.
You don't need the Milodon caps.Save your money.
If you want splayed caps the cheap import caps will hold 650 + hp plus they are less than $100 but you still have to have the block line bored and honed.
It really depends on how many rpm's you are going to turn but I would say the heads are to large un-less you plan on going to 8,000+ rpm's.
Why are you using two carbs?
When all you need is a flowed 750/850 depending on the rpm's.
Your compression ratio is not high enough to use a cam like this.
You would need a min. of 12.5 to 1 to make it work.
Why a solid lift cam?
Why such a wide l/s?
Are you going to use n20?
Why not go full roller or hyd. roller ?
Why are you using such a high rocker arm ratio?
Also I think you would be better off with a 3.75 stoke in a 350 block instead of this 377/380.
