426 small block stroker

I don’t but similar setups are 575-625 range. Has a Hughes roller hyd roller and they did Stage 3 porting on the Edelbrock heads
Hope you get that , I did not get close to that with the big mouth heads , but was runnning a stupid Air Gap intake ported but not enough , with your intake you should get much more than I did . would really like to find an intake like yours
