any info for a fuel injected 460?

 

[Mercules]

intakes?

Greats builds I was surprised to see only one weiand stealth intake in the list. I thought that it had a slight edge over the performer. I guess I'm wrong

I know t5his is a very old post, some of you will give some reminder. But I figure still a lot of guys out there that use this chart to build there motors. Back when I lived in Austin Tx. I built a standered bore 460. Rings and main and rod bearings. The engine was internally balanced. Went to the local machine shop, and the valve grinder or head repair man had a set of dove heads laying in the acid vatt. I ask him how much ands he said make an offer. We settled on $ 50.00 dollars.Back to the junk yard to pirout all the adjustable parts to convert the heads to fully adjustable rockers. Thanks to a set of scrap chevy 454 heads.Comp. roller tip rockers, a ssi cam and kit springs and so forth. 276 x 286 advertised lift with actual lift of 502 int. and exh. x 218 x 228 at .050 lift a 114 degree lobe centers. 3310-2 750 holley carb, edelbrock performer intake with two inch carb to intake spacer. headman 1 3/4" inch primary headers. Mild port work and removed the exhaust bump. Pocket ported the int and exh. I figured 420 to 440 hp with this mild combo. Compression was 9.3:1 after some head milling. The engine went into a 1971 F-100 regular bed truck with a built C-6 trans and stock 9" gears. 3.25 ratio. I out ran a vett with the truck. I only ever got beat and it was a Porch 911, it was very gradual took him almost a quarter mile before he pulled me in high gear. Moved to California had to sell it cause smog laws are inforced heavly. I still miss that truck, it weighed 3750 with me in it. ran a 13 flat @111 mph spinning badly, the track had just had a engine let go spilled oil all the way down the track. If it would have hooked up, who know high 12 second times?. Soo... I will build another one soon, Let you guys know how it comming a long once I get started.

Verify!

So, I was browsing ...............

Came across this thread, and found the various 385 Series build recommendations versus HP ratings. They seem to be reasonable, however while I'm laid up with a blown out back, I thought hmmm, has anyone proven out the posted scenarios, at least from a mathematical perspective? How were these combinations derived? Have they been validated?

Even though sitting and being on the laptop is still pretty uncomfortable, if I take my time, a little at a time, I thought it would be fun to run these scenarios through my dyno sim program, and see how things shake out.

Years ago, I did this on a friend's race engine that was run on a physical dyno, and it was amazing how close the actual pull was to the sim run (within 5 hp!). Let's face it, the engine is an air pump, and all this data can be calculated. The key is accurate input! So, no promises on how fast I can get them done, but I will give it a whirl and post what I find.

Stay tuned (pun intended)!:wink:

Hey guys, I'm interested it taking my motor to the 375-400 hp "level" in regards to this list. I have a 73 block, d3ve heads, 0.30 over with stock type Pistons.

I'm new to it and would like to get some knowledgeable advice, instead off shooting in the dark, breaking stuff and waisting money and time.

I'm going to run it in a 1930 ford coupe. It will way about 2,300 lbs. With a c6. Planning on hitting car shows occasionally the strip and would like to take it on out of town cruise. All the above with reliability.

So my questing are. Are the the d3ve heads topped out at this range?
What stall to run?
What rear gears to run?

 

[Cmfp460]

Did I stump you guys?

I have a 460 harman marine engine that was built probably 15 plus years ago for a jet ski boat. I've had it in storage. Wanting use it to replace my 429. My question is looking at the hp charts. The upper end engines call for 91 octane. Mine has a tag on it that says 94 octane. Before I tear it down to inspect it from storage how serious of a build would call for 94 octane.it has a real nice set of DOVE heads on it, it says boss street rods. Hours of grinding and smoothing the crank. Looks like the shop put a lot of work into some serious machine work. The ad when I bought said it had 19 hours on it.. not sure the guy even knew what he had

Fair to middling..

This is going to be an interesting thread to follow for one always learning like me.
You are going to find out when you tear into it and cc the engine for the compression ratio, take good pictures of the rotating assembly, part numbers and part number on the camshaft. I'm confident you will find Beneficial answers on this forum.

DJ did a bunch of work setting this up. It is however dated and we've continued to learn and refine.

For example.

533 torque 410 hp 460 with mild cam and OEM intake.


OEM style 460 build for 1968 T-Bird
This is essentially an OEM style build with a marine style hydraulic flat tappet cam.

213 / 227 on a 113 in at 109

Stock intake.

Performance valve job on heads, back cut valves. Knock down sharp edges in bowls. NO real port work or shaping.

The output is commendable given the nod toward cost effective.

Same engine with a performer intake and ported early castings is closer to 440 hp.

This simply shows the efficacy of a good valve job with some performance tricks.

Again an example of how much is enough for a particular build AND the use of proper cam timing.

An old school single pattern 268H with 212 @ .050 would be down 25 hp.
