Quote: For a normally aspirated 392, what heads would you prefer for a street engine?
Original 5.7
6.1
Eagle
Apache
Also why would you pick the particular head?
With a street motor that your not going to spin to the moon I'd go with worked over original 5.7 heads. The faster moving air from the 5.7 port will give you quicker throttle response and the low end torque needed for the street. My combo is a 392 with hand ported 5.7 heads and to get the most from them a 2.08" int valve and a 1.62" exh valve. I also D shaped and gasket matched the exh port opening.
Jerry you stoked your 6.1 crank to 3. Something correct? Using a Honda journal? Plus I've heard in order to use a 2.08 valve you need to change the seat? I like your setup and info. Thanks for sharing. Matt
Your welcome. I offset ground the 6.1 crankshaft to a 3.80" stroke then used Eagle 1.88" Honda rod journal connecting rods, .927 pin with Ross pistons on top. With a 5.7 head you can get by using 2.05" int and 1.60" valves with the stock seats.
Thanks Jerry I would love to pick you brain next year about putting a stroked 5.7 in my 03 Dakota. Would like to know if my NGC will run the hemi with a tune? Matt
