I allready have one person that contacted me about building a set. I think I may have some 273 parts left if you need some. I would like to see this combo out there, I think it would be cool if it had a stick behind it also!

as i get my project closer to completion i will call someone for a set, but my question was on the whole car, do you consider 15 to 20k cheap?

Yes I think that is cheap to build a car, I run a 70 cuda in super stock, by all means it's not a cheap car to build. I do all the work myself also except engine & trans. You can't build a stocker motor for what you are saying. Average competitive stocker motor is 20k

and that maybe the reason, we are seeing less and less new cars

I've seen Mark's SS headers. Nice stuff, but out of my budget on the first go around. I'm hoping the 273 will be half of that $20k or less, preferably less. For an engine that will make about 325 HP more or less, I can't see putting $2k rods in it. I think I found the Ross pistons for around $800, hard to say what the ring pack will cost? My idea of cheap headers is the $200-300 ones. They used to make some 1-1/2" primary ones for trucks, but I think they are all 1-5/8" now. I'd like to dyno test with the cheap headers to figure out what size I need before popping for the mid-range headers (sub Performance Welding, above the cheapo headers).

So far, just have a couple of blocks, cranks, picked up some 920 heads at a local swap meet, bought an LD4B and a 1967 273 AFB off Terry Dye. I made a post over on Moparts about valve selection that works in these heads, and some body suggested I put a post over here. So, if anyone has any info they are willing to divulge (buy this, don't buy that, you're a loon for running a Mopar, etc.), please post or send me a PM. Thanks.

did that ld4b edelbrock come from the factory ?? thought it was a cast iron intake

I talked to Kevin at Total Seal and they can supply spacers and 1.2 mm. rings for bore diameters that would work. He suggested that he work with whomever makes the pistons (CP or Ross) to insure the ring groove dimensions are correct. I did get prices from both Ross and CP and the Ross are a little cheaper. The pistons will have to be made to a specific bore size due to ring availability.
I second Frank Castros on consulting Paul Wong. I have only had a couple of PM's from Paul but they had some very good info. He has had more experience with 273's than anyone!

It got added to the engine blueprint specs, not sure when. I'm grateful as the LD4B was easier to find than the flat iron intake.

I think I found some 1.2mm rings in the 3.66" range. Good to know they have the spacers already. I'll check into it. I e-mailed CP to see what their pistons costs. My machinist thinks the Ross pistons are too hard (brittle?).

Paul has sent me a PM. I haven't got much detail yet, but I have plenty of time.

I think this got approved because of the d-dart, but I could be wrong

Paul Wong is the bomb, he is the National Performer award winner . Angela Bushmaker also has a bad AZZ 273 , she runs extremely fast.
