Heart Shape Combustion Chamber Dyno Test

May 18, 2007

We prepped 2 sets of Edelbrock 330cfm CNC ported heads one with the as cast chamber and the other with our modified Heart Shape Chamber, The heads were within a cc or two in chamber volume. The test was done on a pump gas 541 ci engine using the same headers, intake carb, dist. etc. back to back within a few hours on the same day. The test showed a 10hp gain with the heart shaped chamber and peak power was achieved with 2 degrees less timing with the heart shaped chamber heads. This modifcation is available on 72cc chambers only for an additional $300.00. Give us a call if you need more info.
