You may want to pick up a set of the TSP 5.3 stage 2.5 heads. I make 453 whp with them. Flow is very similar to the ported 243s. They have smaller chambers so you get a little compression bump that makes up for that.
I only mention those because you used to be able to buy them with no core and in the $1400 range

What cam are you using to get 453 hp with those heads? I like the idea of the prc 1.0 243s milled to 59cc with my 220 cam to keep power in the lower rpms.
To see those numbers with an auto trans, your going to need a stage 3 or stage 4 cam, with an intake duration of 233 or 238, a good set of heads, a fast intake manifold, a set of 3.73 gears or higher, and a 3600 stall, maybe even a 4000 stall. Then the numbers might not even hit 450 with the high stall on the Dino.
someone on here hit 430-435 wheel with a 224/230 cam, something like that, which is about a stage 2 cam, good set of heads and a fast intake/throttle body setup, through an A4 trans.
if you stick with the 220 cam and the ls6 intake, good set of heads, I think you should be around 400 wheel. You need a 224 cam or 228 cam and the fast intake to hit around 430. The 3200 converter should be fine with either of those cams.
Your car should run excellent with the 220 cam. You don’t have to throw money at it if you don’t want to. Drive it and enjoy, or go for Dino numbers.

PRC 1.0 heads and trunions it is. I must know how this 220r cam/243 ported head combo will work before swapping out the cam again. I have a feeling the torque will be what I'm looking for. If not, at least I'm in the right direction with the heads.
I've never been in a vette with 450rwhp, so I'm not sure what to expect. I know 370hp with a stall rips quite nicely, it just needs a little more.
I have 340 wheel with stock internals, 3.73 gear and 3200 stall, 1st gear is useless on street tires, have to hold it in gear and roll into it. It’s going to be harder with 400 wheel. If I put my drag radials on, I can treat the gas pedal as an on/off switch, and that’s from a dig.
At my power level, tires don’t really spin from a 2nd gear drop at 50mph, unless it’s like 40 degrees outside, then yes, sometimes my 2nd gear will spin tires from a 50mph 2nd gear drop.
Point is, be careful and don’t end up in a ditch, back end can kick hard to the left or right when the tires spin, counter steer quick, let off the gas, and be careful.
I plan on keeping my car, if I do a top end rebuild, it’s going to be AFR or PRC heads, cam motion titan 4, fast intake, and throttle body setup, and all supporting mods, oil pump, timing chain, rocker upgrade, etc. if the block needs to come out, it’s going forged internals, all professionally built, balanced, etc..

How would you rate the benefit of the 3.73 gears with your current setup?
Picked up 3mph at the drag strip on a street tire, not launching hard, wheel spin, best 60 foot 1.97. I have drag radials now. Might be going to the drag strip in 2 weeks.
best time slip ever. I’m car 808.
would love to see a 0.2-0.3 improvement with the drag radials. It should dead hook at my power level.
I like gears. Keeps you in your power band all the time. I usually just drive on the street, no racing, no highway runs, excellent traffic light to traffic light setup or a 0-60 setup, love it. Even at autobahn CC in Joliet IL, picked up 4-5mph on the straits over the 3.15 gears.

OP has 3:42’s, I was trying to bring him to the lower gear side. I’ve had 3.90’s and 4.10’s with a mn6, and I’m a believer. Keeps it in the power band without having to go 80 mph. Used to have a ‘69 GTX 440 with 4.56 gears, and that heavy beast just went right now! Some fun back then…
