18 Degree 434 Chev - That Doesn't Make Power - Help
Hi, I really need some help guys, I put my 434 ci small block chev together about 6 months ago, and had it at the engine dyno, the thing made just over 600 hp, to say I was @#^$%# pissed would be an understatement, I just couldn’t believe the numbers.
I put the engine into the car and ran it anyway, the motor ran fine but my quickest times were 6.41 @ 108 on the 1/8 and 10.03 @ 134 on the 1/4, with a mid 1.4 60ft, car weighs 3140 lb with driver.
I am pulling the motor out of the car in the next couple of weeks to try and sort out why it is not making the power it should here is everything I know about my engine??
