SR20 Upgrades from Frankenstein Engine Dynamics

Looks nice, I’d still like to know how the Dart Heads compare to the Brodix.

Not really an apples to apples questions because there is not one Pro 20 or Sr20 head out there! Too many ports from the same castings. But from what I have seen they are both great heads. For larger motors I'd lean towards the Dart heads, they have a larger port.

I have a Pro20 632 in a 1840 pound dragster that has run mid 6.70's over 197 in good air, normally mid 80's at 195 plus. A friend has a set of SR20's that's a little lighter but runs the same.

When you come home and are blown away! Some companies just get it and take the opportunity to make a statement in branding. The boys down in Texas have figured it out. Chris Frank and Mike Shabareck we can’t wait to represent! #frankenstein. Check them out at FrankensteinED.net

Scott, did they flow the heads when they arrived and then flow them when they left? If so, what were the difference in the numbers? Will be interested to hear/see power gains on track as well
