building my first 454 want it nasty, what heads?

A mysterious figure named Darko
Check out the deal I got, This guy bought a 63 impala that had a new motor and trans that the previous owner had rebuilt but never fired, he ended up selling both of them to me for 1k. Here are the specs on the stuff I got

2 bolt 454 block bored .030 over
steel GM crank
I need help identifying the rods, they look stock & aren't polished
TRW L2349 forged pistons, 11.18:1 comp with 109cc heads
balanced
It has mis matching heads one 3964291 and one 3919840 both rebuilt. They are closed chamber rectangular port 107&109cc heads
not sure on the cam specs yet since i havent removed it but its a hyd flat
fairbanks 3500 stall converter
rebuilt th400 trans that I don't know anything about


this stuff is going into a 67 camaro. It has a 3.55 10 bolt now, but I'm most likely going to go with a 4.10 12 bolt. It has 275/60/15 wheels

I'm going to go through the motor to double check all the torque specs first of all, and now I gotta figure out how I want to build it.

I want an absolutely nasty street car, I want the rough idle, I want to break the tires loose at 45mph, just all out badass.

My first problem is that I want to run 93 octane without having to back off on the timing so I'm looking into larger chamber cc heads. A 119cc head will get me at 10:1comp. I plan on running most likely a solid flat tappet cam ground by jay allen over at camshaft innovations close to here, I will get the hooker 2" comp series headers, and I have a NOS cheater system that i'll be setting up for a 150shot most likely.

So my main questions are whats the best moderately priced head I can run capable of getting me into mid/low 10's naturally aspirated while running 93 octane?


how can I identify which rods I have?


How much are the heads I have worth?


Is it possible to open up the trans and be able to tell whats been done to it since I know nothing about auto's?


How much can the th400 handle?
 
AFR is all I will say...
I would say there 315's..
but there are big Chevy guys on here who will be better to tel you about that
Great find/buy man!

Good luck with it!

Talk to Gary (grr456) :angel:

I have on my BBC, the aluminum Edelbrock Oval port RPM Package, I was very happy with them (out of the box) and not bad as far as pricing!
 
up 4 sale is my top half 990 heads,comp cam 11-605-5,crane r/r ,team g intake (4500) push rods went 10.90s in my 3710 pound camaro all you need :rockwoot:
 
I would look at a set of aluminum heads to help with the weight. Any way you plan on going plan on spending some cash.
