So far my initial impressions are, I can't believe what a balanced setup this is. It pulls VERY hard at every RPM and at all speeds. I love this head and cam combo mainly for the fact that it achieved what I wanted which was a strong running car at ALL RPMs, not a top end car with a mushy throttle under 4000RPM, and not a bottom end car that stops pulling at the 1/8th mile. I would recommend it to anyone who is looking for the same.

How much power is she making? What will the trap speeds be? I should find out hopefully in a few weeks.

I know SOTP is not an accurate way to measure it but it easily feels stronger than any stock C6 Z06 I have driven even though I'm still running Alvin's base tune. If it is or not remains to be seen but so far, I am freakin' lovin' it!!!


P.S. Hey Ricky!! Hurry up with your car so I can come up to Barrie and kick your butt!!

 

IT'S ALIVE!!!!!!!!!!

 

Great job!!!!!

Hmm, so that's what my Corsas could sound like.... I'll be starting mine back up from a 5 month slumber later today or tomorrow!

 

I almost forgot to mention. I grabbed a temp switch that closes at 200*F and installed it into the driver side head wired up to an autometer pro light in my left vent. Any issues of cooling and I'll know way before it can do any damage.

I highly recommend this especially for electric water pump users.

 

Did I mention my cats are ummm...missing!!

 

I love it!!
Makes you want to pull up a lawn chair behind it and listen to that idle til you croak from carbon monoxide poisoning.

Nice job, obviously youve thrown a lot of work at it. Cant wait to hear more on this.

 

I remember when I first bought my Vette after driving a big block Olds Cutlass for 10 years. I loved it and was very happy but I still missed that thumping camshaft sound..........not no more!!


I must admit though, the heads did not flow as advertised.....they flowed more!!

Intake

.200....155
.300....209
.400....257
.500....288
.550....299
.600....305

Exhaust

.200....128
.300....171
.400....207
.500....230
.600....238

For those people counting, thats 2 CFM more than Ricks heads flowed!!!

 

just touching the rim of it on his face huh?
When is the money shot coming.






Poor Ricky,he takes a beating....

 

When we meet up for a "Pinks style" armdrop in the spring!!!

 

very nice job !, I can appreciate accomplishing a build like this, it feels good to finally hear the product.

 

What heads flow more than the manufacturers claim? BTW, those dry flow numbers mean nothing... and you are a leg humper!

 

I'm so glad I built the 396, now I'm spoiled. Welcome to the club

 

Very nice!

Keep us posted on the dyno and track results.

 

Sweet!

Break it in good and run it hard!

 

that thing sounds awesome! congrats.

 

Looking forward to seeing how it turns out

 

why offset rockers on 195 heads?

 

Sounds pretty tame !!

 

[Ricky]You didn't get a Miniram, not a 421, "Eagle sucks" , so power is being left on the table[/Ricky]

Just bustin' on ya Rick.

By the way, that car sounds like it'll tear a hole in the pavement. Nice!!

 

Wow!! Very nice job And it sounds awesome


Any idea of HP ?
