Modern Muscle, I got a very good deal on a set of your HEMI Big Gas Heads. Although I will not be supercharging, it was way to good to pass up. That being said I will be having them installed on my 6M 392 along with the most aggressive cam profile and long tubes to compliment them.

My question is, do you guys have any idea what this set up will yield in additional power?

If all is coming from stock and no other mods, my guess is 75-90rwhp (90 is me really reaching for the stars)

I'd say 75 is pretty realistic

Well, car goes in at the end of this month. So we will soon know. I'll update.

Do you know your base numbers to know what you'll gain thereafter? Who's tuning it? What kind of cam or cam specs you going with?

[Teddyp]

Base numbers were run last year, different shop, different dyno. If memory serves me right I want to say it came in at 426/429-HP/TQ. That's with some minor bolt ons. As far as cam specs, it was ordered this week and the builder and the shop doing the actual grind are getting together on that. I'll have the specs shortly and post them.

I would say around 60 RWHP conservative

Damn I would have figured a little more hp with that LT, head, cam, combo, I picked up 55-60rwhp on my 274 comp cam alone.

We will see. Car goes in last week of May. Can't wait.

I would be very interested in seeing what they do for you in the cam spec department.  When I get back home I plan to see how much we can get out of the stock 6.4 shortblock with a thitek head and custom cam combo.

Hopefully I'll get the specs on the cam this week. If/when I do I'll post them.
