Advice: Solid Roller or Hydraulic Roller for street car

You guys are amazing… thanks for all the valuable feedback. As a total novice when it comes to this stuff, i just don’t want to buy a hydraulic roller set up then wished I’d went solid… or vice versa. As you can see from some of my earlier posts I’ve been researching heads for a while now.. I’ve done the mental exercise of what magnum heads would entail, 302’s, EQ’s, my old 587’s, Speedmasters, and finally came around to Trickflows. I’m pretty set on keeping the 318. I do like the idea of a high revving small block. I’m sure eventually I’ll build the bottom end, but for now I want to run what I got…I’ve stumbled across a few 318’s with stock bottom end/trickflow heads that are making impressive power, using solid roller. This is one: https://youtu.be/o_rGgaJ169U?si=E6TO_GF89QVspGZl I know he’s since done a full build but I would love a 318 running 7’s in the 1/8th (mid-high 11’s in the 1/4), which I believe is probably around 400 hp.

A brief overview of what mine has for anyone that wants to know: 1406 4 barrel Edelbrock Carb, Weiand Stealth intake manifold, Dougs D453 headers, 2.5” duals all the way back with H pipe… Stock 2.76 granny gears at the moment. Currently very mild.

The car feels “peppy” but not fast by any means. My butt dyno believes my current set up might be around 190 at the wheels… pretty laughable. I know heads and gears are holding me back quite a bit at the moment, so those are the 2 things I’m taking care of asap, but due to budget it’s one thing at a time…
1 st What rear gears you willing to run?
Ideally you want to be able to get into the powerband at average road speeds, eg.. drop it into 2nd around 30-60 mph and mash the go pedal.

2.76 in 2nd @ 30 mph = 1550 rpm, 45 mph = 2325 rpm, 60 mph = 3100 rpm
3.55 in 2nd @ 30 mph = 2000 rpm, 45 mph = 3000 rpm, 60 mph = 4000 rpm
4.56 in 2nd @ 30 mph = 2550 rpm, 45 mph = 3825 rpm, 60 mph = 5100 rpm
plus stall and slippage factors in.

Main powerband is usually around 2000-3000 rpm Stall to Shift points.

2nd what is high revving? a 400 ish hp 318 peaks about 5900-6200 rpm, shifting around 500 rpms higher and peak tq should be around 4500 rpms, which is even higher than 4.56 @ 50 mph.

3rd what size cam you thinking? Is gonna be the crucial pick to make all this work.
