Rusty I have a couple of questions about this. Generically, would 12 degrees of initial timing be about right? Second, if he has closed chambered heads, wouldn’t those be more efficient and need less timing? Initial or total? He didn’t mention if he has 340-specific-edelbrock open chamber...

Also, engine manufactures sell 3.9 short or long blocks usually cheaper than the sum of machine work and parts for some engines

Lacquer thinner mixed with transmission fluid (or better yet super creep) sprayed into the spark plug holes with an oil can. Maybe, additionally, pull the oil pan and spray up into the rotating assembly. Should loosen things up. There are automotive ‘snake-oils’ that are so thin, they soak into...

Beets help don’t they?

That shop did ALLOT. of CUSTOM. W O R K ! ! ! It is in the article. Best bet would be to have that exact shop repeat the build for you $$$$$$$ because that shop owner would emotionally remember what it took to build that engine build. The moment he starts pointing you down a different path...

It’s time to get your property and find another machinist/engine builder. SOME business owners are disagreeable when they don’t want to do something-I’m hoping this is your problem and not ignorance/greed-w/dishonesty.

Replacing the piston and balancing the assembly is literally right up his alley, his forte, HIS JOB. Tell him you want some KB-107 +.030” (or Speed Pro H116cp pistons) pistons and rebalance it-you will have everything you want. It’s your engine/money, wtf does he mean “No.” (to replacing the...

I didn’t read all the replies but you should be able to mill the cylinder heads and the deck height of the block. Quench is PRECISION measurements and timing-at that close, there is a risk of valves kissing pistons.

The valve lift and rocker ratio are limited (I believe) by the flow of the intake/exhaust runners. On the iron j heads I wanna say the experts here said lift after .45?? Was a waste on stock heads. I don’t know what the limit is edelbrock heads. You have given engine specs, but Everyone here...

I have had a machinist use the profes sional products balancer before, the machinist was an older fellow and didn’t seem to know any horror machining . He couldn’t do more than 3 angle valve job not insert valve seats into a cast iron J head. The professional products balancer is what he...

I'm also interested and will send you a PM

Flywheel yes, I was looking for the damper that the machinist could adjust the weight with (it came with several weight options) -but have blanked out on the name of that balancer.

H116cp pistons wrist pin and rings are lighter than stock 360 pistons (360 pistons alone weigh 584 grams, LA pins 153 grams? LA rods 758 grams? H116: Pin Weight Gram 154 Weight W Pin Gram 736 Weight w/o Pin Gram 582 Aftermarket I beam rods are lighter than stock…Weight is approx. 595...

MAybe ‘I’ Should build this 340” 318 since I already have two of the 3 needed parts. The stroke would work good in a mild truck.

If this legitament, I have the mopar con rods 6.123” with Chevy-sized wrist pin journals as well. But you would ONLY have to pay the machinist to angle in some correct-angle valve reliefs into the pistons.

318 340 Mains

I have a (?yellow steel?) forged 3.51 crankshaft, but you would have to order custom pistons-it should put you into the 340 cubic range sir.

Do you have the pickup for this oil pan or the pickup’s part number?

That doesn’t look like a Milodon ‘Zinc-coated’ pan, just gold paint. Did you repaint it?

Racing head Service? Engine Quest- I believe that these heads you bought and ported are based off of the RHS iron head from a while back, which engine quest copied.

So many photos are missing. Why is that? Can we fix that?

Honest question for you sir. You are one of the most prolific experienced automechanics on this forum. You could build a slant 6 or 318 Mopar A body for less than a new car; why chose a new Mopar with a 3.6? Is it because financing is a faster path toward your goal? I know you could build...

horsepower is torque over time. that's it. a measure of acceleration of torque. end of story.

I looked down to change the radio at 160 and had shifted lanes in a blink. new bushings and a tight front end was quintessential to safety, my friend with a 70's charger said his would lift up at 140mph-aerodynamics and that giant air scoop being all the physics stopping him at 140. Not the...

$120 cleaned up, polished

I agree with your definition of Horsepower. But essentially a single piston briggs and straton engine making 75 hp and worn chevy 305 V8 making 75hp NEGATE your opinion;torque is what is going to move the vehicle (outside of gearing) and rpm will dictate the final speed of the OP's objective...

there are other factors, wind, traction, friction input vary at varying speeds, (pressure from) altitude, -but basically like you said, "59hp 76ft lbs" gearing is like Archimedes? lifting a ship by himself with pulleys. It makes up for the torque to some extent. As a point of interest, the...

By horsepower you mean torque and gearing. Acceleration does not have to do with reaching top end power for the sake being at top end power.

I guarantee it. I have driven 60-90hp/200 ft-lbs torque engines 130. CelloMom on Cars: How much horsepower do you need? (cellomomcars.com) How Fast Can a Car Go? (itstillruns.com) HP required to go 100mph? (pro-touring.com)

And no, the engine won't bog down with high gears
