Plan A Head Stroker Heads To The Maxx
Promaxx heads sbf review. Hi guys unfortunately i am going through a rebuild on my 87 302. Maximum quality maximum performance and minimum pricingpromaxx maxx series sbf cylinder heads take affordable power to the next level. Go out and shock the competition. The cnc ported 340cc versions from promaxx featured a 230188 stainless back cut and swirl polished valve combo 122cc combustion chambers and intake flow that exceeded 400 cfm. The professionally designed cnc port flows like the top brands in the industry over 325 cfm. Compare flow numbers and then look at the price.
There are a ton of options out there. Even the as cast heads utilize ultra smooth new runner and chamber designs that produce cncd type flow numbers. Test results always look amazing when you replace the one bottleneck in the system but it does illustrate the importance of planning ahead when choosing performance components for your stroker ford application. Promaxx performance cnc ported ford sb 289 351w aluminum heads these full cnc ported heads are what the small block ford stroker engine wants and needs. It puts out up to 20 hp over the competition. Flowing over 328 cfm through only a 210cc runner will make the power you need from your big cubic inch small block ford.
I am looking for an option that doesnt break the bank because i am also going to be purchasing a different carb. Truth be told the 393 stroker was much better suited to the flow offered by the promaxx heads as the stock versions were designed for a fuel injected 302 rated at just 225 hp. The cam i currently have is a b303. Though promaxx offered both smaller as cast and larger cnc ported heads featuring 370cc intake runners we opted for the middle of the three available heads. It is a stock rebuild but instead of reusing the gt40p heads i have i would like to get a set of aluminum heads. The shocker 210 cnc sbf heads are tops in the industry.
Compare performance and price and you will see it is no contest. The promaxx maxx series small block ford aluminum cylinder heads are taking affordable performance street and strip cylinder heads to the next level.
