Right now im looking at turning my 500ci 440-1 as a good spare engine for a pulling season. The mid 800hp numbers it makes wont really cut it as a spare.

Im stuck in the middle somewhere. If i go bigger cubes the heads wont really be big enough. If i go bigger heads (b1's) i've got to change pistons and than my stock block 500ci probably wont like the new hp.

If i was smart i would have went b-1's first and than moved up in cubes later on.

If your happy with 800hp stick with the -1's. Dont even consider the 572-1. and if you want 900hp+ go b1's or the b1'MCs

greg, thanks for the ideas, i am running 440-1 that was cnc ported by indy, they are 325cc intake port. so there is more to go if i need it, and posssibly could with a big bore.






Too bad I haven't had a chance to try out my 2.300 intake valve 440-1 heads yet. It would be great if I could say you will pick up XX hp from the mod. Sounds like your estimate of your current hp is a bit low, as you already have the heads I thought would make a good upgrade. It will be tough to get a 70 to 100 hp gain out of the same heads, unless your present motor is low on power for some reason. Have you had a chance to compare power output with other guys running the same heads?
Would you mind posting a full rundown on what you have run for a motor?

your about right .1 in et plus block weight, my stock block, filled weighed 254lbs so i am not that far off an aftermarket weight

i am not impressed with this cam either, but am afraid of going wild with it, the rockers probably can't handle any more spring.

just want to make a plan to start buying parts, looking for bargains

thanks lee

am i missing something here? not trying to sound like an a h0le but the OP has two sets of -1s and seems basically happy with the times his car is running. it also sounds as if there is a cost cap on what he wants to do. now it's being recommended to take the bore on a new engine out more than necessary to get the job done and completely change his engine program. yes you're leaving hp on the table if you don't max out the bore, you're also leaving hp on the table if you don't put a blower on it. afaik this looks to be a bracket car and the costs need to be contained. a new shortblock with more inches, compression and cam (ditch the dove rockers) will accomplish his goals (and then some), there's no reason to completely change the program. the -1 head will work on the larger displacement. while not as good as the brodix it will still get the job done. like i said i'm not bashing the brodix that's what i'm using but the heads he currently has will work.

Absolutely, I also didnt max the bore out on my Indy Maxx block, I went with a 4.44 bore. Why? In case something happened. I knew I have several over bores before I max out. What kind of power gains could be expected from a larger bore by say .030 or even .060 bore? Would it even be measurable?

I ran this engine in a digger also. My cam was small than yours 275 ish at .050...I sent it in for a regrind which didnt produce any e/t just a lighter wallet. What most people forget at this level gaining a tenth or a few MPH takes a bunch more than 20 or 30 hp...more like a double of that.
The cam is in the ball park
Use the 440-1 heads..
That combo doesnt need a 8inch converter...it is a power glide correct? If it isnt thats half your problem.


ask around and see what most dragster owners are running...I did and most run a 9" converter...
I would opt for full tilt port work on a dragster..The extra flow up top always help, and you dont need any torque below 5K.
This little engine of mine (home built junk) 60ft just as good if not better than any other dragster at the tracks I went (similar N/A bracket jobs)..Even better than 600 cubic Inch engines with there sheet metal intakes etc..
a 727 torque flite doesnt work in these cars peroid. So i doubt you are even running one.

very good point on the bore, leave it smaller maybe put a little more stroke in.

yes it is a glide with 1.80 gears

i am putting a playback tach in this winter to see what the convertor is doing

the new engine will have better parts than this one crank,rods,rockers will all be better

thanks lee

I think 1.7 rockers would help also.

My 528 was 4.500 x 4.150 with 440-1 heads...In a 1950lb 4-link dragster...Good weather it ran 4.76 to 4.78 and hot weather was 4.82 to 4.84...That was leaving at 4600 and shifting at 6800.

Stuff I wished I had done different-
Invest in very stout pushrods, I did later anyway!
Buy rockers with at least a 1.7 intake ratio, higher if the cam profiles I want to use will allow.
Contact someone that knows valvetrain inside and out, to make sure I have a dead reliable set up.
Buy the titanium intake valves, as the money spent will save money in the long run.
Set up my motor for pushrod oiling first time around, again I did it later!
Spend money on a great crank, center counter weighted, as that is what I did later.
Lee, hope this helps your choices, maybe save you some $$ down the road.

What is the best cam to use with these 528 cu in engines in a dragster? Maybe we could all benefit with the right camshaft selection. I have the engine out of mine & could change the camshaft.
Mine is the 4.50 bore 6.570 BME rods 4.15 crank with CNC 572-13 heads. My cam is a Cam Motion Roller R2826-2862-11 with the Jesel 1.7 X 1.7 rockers the specs are .799/752 .283/292 . It seems to work great,but now would be the time for a better one. The same cam might work for all of us as our combinations are fairly close.Thanks

I have a very similar cam to yours with a bit more exhaust duration, and the previous cam was very close to what you run with less exhaust duration. I didn't see a lot of difference.

i wish i knew more about what cam i needed. after i put this one in, i had to change air bleeds in my carb to get it to take the fuel from a dead idle. my carb guy said it probably had more reversion i have the engine apart now and might change it.

I am real happy with my cam now,but could put another one in it if need be. I had a new CO2 shift noid that was nothing but trouble,so I know it will rev up over 7600-7800 RPM before you can get out of the gas. But this is my 1st if you call 528 cu in big engine. I have been racing Big Block Mopars since a teenager in 1977 my best engine before this was a .060 440= 451 cu in with a Comp Cams Roller 286/750 with Zeeker heads. So it may all in the engine instead of the cam shaft. But I do know how they feel when they reach thier peek.With the Zeeker engine anything over 6400 RPM & it quite pulling. Maybe someone can put us on a good camshaft.
