528 hemi swap

As soon as I find the spec sheets from Stage 5 I will be happy to post them for you. These heads are advertised to flow 10% more than stock heads. I built a 426 engine that was totally stock down to the carbs and the distributor but it was recurved customer had it dyno'ed a 490 ft lbs of torque and 531 hp. it was the original engine from his 68 Road Runner. I built the engine in my car 15 years ago and a lot of that stuff is in folder some were. I don't have any thing to prove to anyone I built this car for me. If way one want to go for a ride or see the car just let me know
