No Glenn it would not be nice to make it more standard, as running what you have now is in my opinion the way to go. I like Matt,run the BBF - 385 motor. Back when I started there wasn't many parts to run them on blown alky. I made everything myself, enjoyed every minute of it. An example, I ran a 1968 Lincoln 460, I had the crank offset stroked and ran that cast iron crank, stock block, stock lincoln heads with BBC intake & Pontiac exhaust valves, made my blower manifold from a Offy tunnel ram, stock 1968 Lincoln dist with dura spark pickup, T 400 behind it, in a home made funny car. it ran 7.50 at 3,000ft track, never ever had to lean on it. every main bolt, head bolt was stock. I ran a 390 gear and a 36 inch tire, 6,500 RPM.
That said I reaLLY hate the Chevy= Chrysler mentality. The fact that NHRA has banned the BBF from most every class I want to run confirms that mentality. Keep the Tin Indian please.

Glenn, what makes you think that?
I don't know Pontiac blocks, but is it that weaker than, for example, a SBC? How much horsepower you are making?
Going against the grain is always harder, but way more rewarding. I may put an inline 6 in my car one day, maybe a pair of them.
Now, if you're set in going Hemi way, that's super cool too.

The Pontiac block is inherently weak in the lifter valley, I have been advised that around 850 HP they like to split down the middle. On the dyno this spring it made 813. Since then I have leaned the air / fuel mixture out just a little to get the 8.0 mark (a little more HP).
I do have valley braces in the block and it is a ram air III block I believe I am safe at this point but would not like to push it any more.

why not go with a BBC ? i know they have valve train problems and stuff when you really start putting out the power , but there are alot of guys running stock blocks over 1000hp blown ..... if you didnt go crazy buying high end parts you could put together a pretty reliable bbc for under 8k i would think .
i have looked at the hemi route myself for the car im building , but i dont see myself going faster than 7.0 so the bbc will be just fine for me i think .... ill do a hemi on the next car i build

Glenn,
Good and bad with Hemi thing. Good points strongest thing out there. If look at round and hit up higher class alky cars you can get good deals. Fuel stuff I would say stay away from. Now blocks and cranks you can get deal on thru Holbrook Performance(Jimmy Rector) ,Wizzards Warehous(Tom Aykers).Heads and vavletrain same thing. ROds go new. Intake for blower deal lots around.On heads go with older fuel style for more parts intercahngablity. Old BAE fuel style work great if find a set not beat to death.
Down side parts not a readily available in used market as BBC. Nowhere near as many parts at track if need something. Cost depends on new or used. Im running injected Hemi in my FED.Reason I have 3 blocks,3 almost new cranks and 2 sets of heads plus lots of spare parts. If not I would go BBC.
