TCS,
I have the same SD 330 cfm CNC ported e-heads- planning to run them and the Road Paver on a 455 (stock 4.21" stroke now). Would stroking the 455 to 4.5" make the RP more streetable? Of course I...

The custom 72 Bird has some serious money under/in it- I see why it sold for $156k. If I were to build a car to sell, sad to say I'd put LS power in it to pull the most money out of potential buyers....

Zyman,
Looks pretty good. I'm annoyed with Photobucket myself- here's a recent pic of my Bird with the Bandits. Not alot of rubbing- most of it is due to a tired suspension (that's getting addressed...

My issue is fuel- living in Kommiefornia, I'm currently limited to 91 octane and Dave advised me to set the SCR to 10.25-10.3:1. I have his 325 cfm CNC e-heads. Eventually I will run a stick, but the...

I built a 326 for a customer who wanted to use what he had, but still wanted much more power than stock. We ended up going with custom heads from KRE. They set the heads up for a 56cc chamber,...

They would probably be okay for an all- cast iron street motor that you don't rev past 5500 rpm , but I wouldn't trust them in an aluminum headed build, or anything high dollar.Roll the dice and let...

You make the Speed Pros sound like they are the Sterling 8 valve relief pistons-lol. They aren't that bad, Cliff.

A Holley 750 cfm vac.sec. will feed a 428 just fine, but clearly you'll need bigger jets to feed a 428 vs.a 350p. A DP is better suited to an engine with a bigger cam, less vacuum at idle- a vac....

You guys are suggesting $500- 600 pistons to the OP? It doesn't sound to me like he's trying to build an all-out race engine. Sealed Power forged pistons are fine for his application- pressed pins...

Ported iron heads with the right cam can get 475-500 hp from a 455- pretty much what a set of out of the box KRE heads can do. Other than the weight reduction, the main advantage of going with...

No.17s give you a 9.3:1 SCR on a 400- you'd have to mill over .050" off the deck of a set of 6x -4s to take the 94- 91cc down to the same 80cc. It's better to have the bowl opened up and 2.11s...

I posted this thread because I've never built a 455 this aggressive before- my last 455 had ported no.64s, a Crower 60919, 850 DP on a T-II, but it also had TRWs and cast rods w/ ARP bolts, so I...

My 455 has a 4.171" bore, piston - deck is .0015", chambers volume at 85-86cc- I'd say the SCR is 10.4:1. The car currently has stock rotors and single piston calipers (rear off a 79 WS6 TA), and the...

Road Paver or similar roller cam?

I finally got my 325 cfm e-heads from SD Performance, so now it's time to get the valvetrain. I told Dave I want to run the Road Paver, and he set the heads up to run this cam. I have a 73 455 2-bolt...
