Advice: Solid Roller or Hydraulic Roller for street car

Shane65 said
Looking at trickflow heads for my very mild 318. My car is a street driven 68 barracuda, weekend car, gets probably 3k-4K miles a year if that… i definitely want some HP gain with this project, but not sure what the best route is. If I go hydraulic roller it’ll probably be less maintenance, but how much power am I leaving on the table vs going solid roller? I’ve heard some people say they run solid roller on their street car no problem heard others advise against it. What do you guys recommend. Again I’m not trying to break any track records but I want the project to have worthwhile gains for the time and money spent.

Beautiful car, looks very much like my wife’s.
We run a Hyd. roller in a 360 with the TF heads and a TTI exhaust stem to stern. The intake is a RPM AG & a 750 Holley.
The trans is a 904 w/a custom re worked converter to meet the camshaft specs, cars weight and the 26 inch tires being turned by 3.55’s. Cam card below.

Also, member 273 makes a mention of where the engine will leak power wise with those heads and while the slide ruler and abacus calculations lean in that direction, what truly dictates the upper rpm power able to be made is more the camshaft at this point since taking advantage of the TF head in full isn’t a street cam but a pretty sizable SS or race cam with seriously aggressive lobes and mega lift.

On the cam below, I used 1.6 rockers to help a little in the engine breathing in the rpm range of what the cam will perform in, and it’s not 6500+!!!!!!

I can’t magic crystal ball answer a HP difference on un specified & unknown cam events. Honestly, no one here can even if they had the cam specs listed.

Trick flow is a lot of head for a 318, there gonna want to work (make peak hp) in the 6500-7500+ rpm range with a decent cam in a 318.

Anything done to the short block? like zero decked at least.
