EQ Clyinder heads vs 441 487 993 GM heads worth the cost

Parrot what do you think each engine built by the rules would make torque and horsepower wise I know what the mopar makes on the dyno a little over 410 TQ and HP at 5800 rpm 6100 is the limit on it. The TQ and HP are nearly the same I have heard rumors that some of the Chevys we race against made450 hp but this was with a week of dyno time. at who knows what cost. We can not afford to put our chevy on the dyno but I think it be doing good to make 400 on either one the HP might be there but not the TQ but we can put more gear in and spin the Chevy to 6700 which might help some don't get me wrong if we could go Mopar we would in a second we just need any ideas that might help max out our combo without dyno time I think our motor is probably similar to a 602 but with out the vortec heads and a 425 lft cam .

GM always claimed 10 cc larger runner but I have never tested. Guess they was just "blowing smoke"! lol

Im not sure. I have heard that they had 2.02 1.6 valves to, but my neighbor bought this truck new , so i know it came from the factory and hasn't been messed with.

The torque is what makes the Mopar so strong I mean up this thing would just eat the best of the Chevys up from the middle of the corner off I mean to the point of lifting to keep from running over them it was quite impressive I ain't had nuthin pull like that since I raced 440 Mopar big blocks years ago those things would your pull your eyeballs thru the back of your head you drove them by aiming and holding on LOL!!!!

Hey thanks to everyone especially Parrot for the info .We are going to stay with the 487/993 type heads because we have them and the general consensus is they are not worth the cost especially in light of fact they are heavier.Also all jokes aside we are building whole motors for just a little more than Parrot says it would cost to put good parts on the EQ heads.We will continue to build our 1500 dollar grenades they have worked pretty good so far 1st one lasted 2 seasons before it went ka boom!!! Thanks again everyone.

I used to love building those "1500 dollar grenades"! LOL We ran em in the ground forever! Old bomber would scream with them! Now the days of Mod and Late Model engines and my Asphalt motors have left me wishing for those days!
