The Value of a 1964 High-Rise 427?

[FFR428]

Well that's what you need to know.....about the cranks and rods etc... That would take away a little value if your looking at a iron crank and bolt and nut rods. Roller lifters like oil getting to them via the lifter galleys like hyd blocks have. You don't get that on a solid lifter block as the oil galley to the lifters is not even drilled. It was not till the 68 427 that the 427 blocks were drilled for hyd lifters. My old 406 was a solid lifter block and I wanted to use roller lifters. I was told it's not the best idea in a street engine by several people with way more experience with them. Being the lifters oil from splash in a solid lifter block there is not a whole lot of oil that gets to them at lower rpms. I've run flat tappets till the cows come home and have been very reliable for me. So I took the advice and stayed away from the rollers in the 406. I'm sure there are a few guys who have run rollers in a solid block. Maybe they will chime in with their experience.

Hard to comment on the TP vs HR engines. Each has their plus and downside. I think they are close with the HR having the edge. The TP heads and intake will fit under the hood tho. This is my first tunnelport so I don't have a whole lots of feedback yet.
