I currently built a 408 windsor i wanted to get the compression high but with this stroker i bought, it only had flat top piston option or dish. With flat tops my compression ratio is 11.7:1. I built this engine to race no street time with this. I need a second opinion if i should order a set of dome pistons from diamond pistons ( which i found the only place that offers them) which will make my compression 13.8:1 with a 62cc combustion camber, and the heads are dart pro1 cnc 225s is it worth spending the money for higher compression???

I would stick with flat tops unless you plan on running race fuel only. If so it maybe worth getting the domed. But even then you will need a good tune to run that high of compression which I'm sure you know, just wanted to throw that out there.

I degreed the cam to the cam card nd it worked and also the valve reliefs r .270 intake/.200 exhaust and the dome pistons i was looking at have .300 intake / .260 exhaust nd the valve pockets r 2.15 intake/ 1.70 exhaust im pretty sure they will work but im gonna call it in to check and double check bc i dont wanna buy sumthin thats not gonna work

Thanks! Yeah i did alot of research before i built it, nd if i can get more compression i wont need nitrous nd have a pretty stout motor =)

No one including the manufacture can give you an exact yes or no if it will work. The only for sure way is the clay way. Did you have it running the way it was yet? My neighbor has a similar setup and pushes 700+ hp n/a!! Except hes poked and stroked to 427.

What size carb do you have? With the compression you are trying to run I would recommend a wideband a/f gauge. Have you seen my wideband setup in my albums? It's in my custom radio delete. I installed a multimeter next to it to keep it calibrated and add the accuracy of digital. You can search "how to calibrate a wideband". If you can't find it let me know and I can search it up if your interested. The multimeter was 4$ and works great. It's a gauge for my gauge.lol
