Most HP out of a 525
Just curious whats the most HP you have seen out of a 525 without using a supercharger or turbos? I went down to bare blocks and am almost done putting them back together with some goodies. Dyno runs will show if it was work it or not

We found really good gains with the 525 just by going to a big bore. With no other modifications other than a 4.600 bore and ECM tuning to correct air/fuel we picked up approximately 60hp over a stock 525. Final number on the dyno was 610hp. Stock 525s constantly make 550hp on our dyno. By no means claiming to be the highest number from a 525 but we were very happy with the gains

The 525 intake runes out of air flow in the low 600hp range. Opening the mouth helps but its restrictive in other places. I did build mine last year made them into 540's opened intake and cnc heads stock cams and dyno 620 hp. But the motors gained a lot of torque. I gained 7 mph over stock 525's in a 42 Fountian.
