Ok I just looked over my 429 and got the numbers off of it. Maybe Dennis or someone can tell me if I have anything out of the ordinary or something I dont wanna use.
Block-C9VE-B
heads-DOVE-A
Crank-4U
Rods-C8VEA
Pistons-C8SE
Its got two valve reliefs in the pistons and looks like 2.010 intake and 1.65 exhaust or there abouts. FIlle me in!

Hmm...honestly...you have the right heads, block and all....the only thing I would try to find are D0OE Rods. These are the strongest 429/460 rods made second of the NASCAR Rods. Other than that...you have a perfect combo there..

How high would the compression have been on this? Where would I get those rods, and whats the best slugs to attach to those rods? I figure on using an Xtreme 4x4 cam with split duration. Id like to run this on pump gas, so Im curious if this has high compression, will the cam help it enough to run on 89-93 octane. Its got 2 bolt mains, and its out of a '69 tbird, 4bbl.

 

The D0OE-R rods are kind of hard to find. The D6VE-AA rods are much easier to come by and are suppose to be the same as the D0OE-R rods. I believe they were used in most truck engines from 77-79. It sould be 10.5-1 compression stock.

The D0OE-A rods are hard to come by like 79 said. I was lucky enough to have them in mine when I bought it. The D7VE-AA rods would be the next best thing. These were the truck rods first produced in 1977 and are just a durable. It'll have an 11.0:1 compression as is. The compression ratio dropped in 1972 and 1973 to 8.0:1 which is what mine is. That's why a lot of people try to look for the older heads like you have to bump up the compression ratio to around 11 or so. I don't see why you can't run yours on regular pump gas. Most regualr 429 blocks are 2 bolt mains. The Cobra Jet, Super Cobra Jet, Boss 429, and the D7TE, AND D8TE blocks all have 4 bolt mains to them. If you can find one of these you'll really be set to go. The truck blocks are easier to find though as compared to the CJ's and Boss blocks. I hope this helps you out some.

So are my rods even worth keeping? Overall, the insides of the engine look good, no abuse, but its been sitting for 4 years in pieces. It needs a trip to the shop. I dunno how the bores will measure out, and how over I will need to bore it if any. Any good brands for pistons? So I should be able t orun pump gas even with the high compression, and say the compcams 34-235-4?

 

Your rods are fine for the RPMs your gonna turn with that cam.Have them checked to see if they need to be resized and you could put a godd set of rod bolts on them.I think you'll be happier with the motor if you drop the compression some.As I said in another post I have the same motor in my '77 highboy.I ran this motor for 2 years with the high compression.It ALWAYS had to have 93 octane and could't have the vacume advance hooked up.I had to run the timing retarded to pull anything and it would still try to over heat from detonation.Then there is the price of 93octane,right now it is $1.50 a gallon and most of last summer it was $1.75 to $2.00.So with a truck that got about 9-10 mpg I didn't drive it much.It now has aset of D2's on it and it will run on 89 octane and pull a load with the vacume advance hooked up and the timing set at 10 degrees.The truck is more fun and trouble free to drive now.Sorry this got so long but I don't want someone to go through the same thing I went through.

Hmm, well I could have the heads opened up some, couldnt I? I am thinking of a Holley 750cfm, Weiand stealth intake, the above cam mentioned, line bored and balanced, and headers. How much difference will I see, between a lower compression say 9:1 as to the 11:1? Any desktop dynos? Someone, please tell me where to get that program so I wont bug ya,lol.

 

Shops don't normally work on the combustion chambers.My motor with 9.5:1 and the same cam you want is making 427HP at 5000 and 497lbs. of torque at 3500.The same motor at 11:1 would make 455 at 5000 and 523lbs. of torque at 3500,BUT these motors were built to run on 100+ octane that was available at the pump in the 60's and early 70's.I got my desk top dyno from Summit Racing.

[updated:LAST EDITED ON 02-Apr-02 AT 11:07 PM (EST)]Heck thats not that big of drop for the cost difference in gas. Id just hate to give up those heads, unless theres some lower compression pistons out there. WHat if I dropped a 460 crank setup in it? I seen on summits website dished in 460 pistons, but then would switching to a 460 stroke jack up compression?

 

Whats the specs on the comp 34-235-4?

 

advertised duration- intake:262, exhaust:270
actual-I:218, E:226
lift:I.514, E.524
lobe seperation:111 degrees

Im wondering now if I run dished pistons and a crank out of a 460 with my DOVE heads, and a stealth intake, with a 750 cfm, and headers what kind of numbers I could realize.

 

425HP at 5000
525lbs.of torque at 3000 to 3500
