It's happening guy's !!!! I'm starting to see Pontiac traditionalist come back to running a traditional Pontiac V8. It has take a long time, but guy's that jumped ship and went with a Chevy engine are starting to return. I have had three calls in the last week from guy's wanting to build a traditional Pontiac engine for their Pontiac and sell their BBC or SBC. Their argument was they could not buy the parts they needed or wanted to run as fast as they wanted. Things are changing, it's just to bad it has taken so long.

That's positive news!

Could not buy the parts they needed ? What in the chevyworld can that be ?

Don - that is great to hear. The work you've done with the Tigers and RA-V play in important role it this.

I know I am going to sound like a fan boy but it is not meant that way. I firmly believe that Big Chief had been a key reason we are seeing this revival. His demonstrating that Pontiacs run hard reliably and can be the top dog on TV the last 4 or 5 years has woken people up.

Good points Gto Dan.

Part of reason I want to build something same size as typical LSX combos out there(455). We have some nice strong weaponry to chose from whether we stay somewhat small or build a 572.

Think I can build a 4" stroke 4.255 bore 455 that makes over 750 na hp hopefully on pump gas. Lots more on race gas or e85.
Plan on stuffing in either a nice 1st gen or 91-92 3rd gen. Probably auto with OD but a 5-6 speed stick might be fun to try .

Sounds like a cool build!

Bruce, I know this might sound like a sales pitch and I don't intend it to be, but you can if you use my RA5 heads. We already done it with an independent dyno not our own and confirmed interdependently at the track. I chose not to do it in house or in my car so no one could say I fudged the numbers. I used a 455 factory block with stock stroke and 4.155 bore so I could show case my heads ability to work on a small bore. I Used a hydraulic profile cam too with 10.4-1 compression. Jim Robertson on here dynoed it for me in Texas. The engine consistently made 750 to 760 HP, and made 780 a couple of times. It actually showed a little more in the car, but I attribute that to having a hood scoop with a positive pressure on the carb.

Thank you Dan for the Kudos. The Tiger head was a huge leap for the traditional Pontiac V8 and has proven to be a good platform for 1,000+ HP. For the guy's willing to step up to the plate and spend the money it has even come close to 1300 HP. I really hope that my fairly new to market RA5 heads can top that once some of the big players start to use it and figure it out. I really do believe that my DCI RA5 heads on a 4.420 bore can flow 550+ CFM with a 2.400 valve. That will hopefully take us to the next level. The math says we can get real close if everything is right. Time will tell !!!!

In the Chevyworld there are many with no idea who to call or trust.
Why some cars with a 540 are stuck running 11s

So I could take a well prepped stock 455 block ,use these heads,intake and exhaust with a well chosen cam and bam,,,,750 hp? How much torque and how many rpms to reach that 750 hp? Makes me wonder why I went with e heads,vicor and a dominator for 625 hp.
