Do these engines have hydraulic roller camshafts? Any important differences (besides oiling and rockershafts) between the engines? I believe the camshaft snout is somehow different but I don't remember. Didn't someone here mention that using a J head on a roller 1988-1991 360 engine had issues...

I noticed that 1 my SBM was cobbled together, belt pulleys don’t line up. 2. taking off the alternator, fan, water pump, and crankshaft pulley & comparing them to other pulleys, water pumps, even power steering pumps don’t all extend forward the same distance from the engine. 3. while trying...

That one seller on eBay sold those Mopar length connecting rods with Chevy sbc sized wrist pins. couldn’t someone match a set of Chevy pistons with that crank and those cheap rods up to a 340 , R, X, or 318 block? (Fairly easily?) if the big league guys here are not jumping on that it might...

Or is the torque band strictly dictated by engine displacement and camshaft? Just curious, Thank you

i was watching a porting video on YouTube and they mentioned carbon buildup. I look it up on the web and most references relate to the problems created by direct injection-which I understand. 1. How bad is it? Is this correct: “You might already be aware that an additional heat buildup of...

Was working on my grandfather’s old ranch (split to all the aunts, uncles, one cousin, & momma) today when I came across a 5.9 magnum equipped 2500 Ram extended cab truck rotting on a hidden portion of the property. I ask my cousin what’s the story- (It has bald tires) Someone rolled the truck...

just FYI for you guys

273? 318? 340? 360? 408? 4++? We talk about velocity in the port for intake (at atmospheric pressure), BUT the exhaust is pressurized.. ? -Is the only concern a choke point of exhaust flow out to headers? THANK YOU!!

I have both of these. This particular build is a Street build, <4800 RPM 99.99% of the time. Do you think the rattle of the rhoads lifters bouncing off the cam would destroy the rockers (vice stock rockers or 273 rockers) ? After reading all of you guys input on the SBM board I know that just...

Do we have to special order this oil or can you pick it up on the shelf somewhere

360 build I am looking in the SBM forum threads, but just don’t know enough. What works better for the machinist for balancing? With the above parts, & a machinist that is going to balance the assembly, what harmonic balancer would you guys recommend? (Manual transmission) internal balanced...

If you give the machinist these pistons, and stock rods- he tells you the pistons are NOT for full floating wrist pins (supposed to be pressed fit), can't he fix or adjust for that himself? better solution? thanks

My buddy used flex plate bolts from a Ford 351 I believe. Are Chevy, Ford, the same as $$Mopar$$ flywheel bolts? Please help, THANKS!

I bought a 360 block from a jacksonville drag racer for $60. block was supposed to be machined, including line honed, was .040 ,,late 70's block a hone would not clean it up, they bored it out to .060" -they had to sleave only one cylinder for $125. I plan on using this build/engine as a LOW rpm...

I believe I read that several people (here on the forum in different SBM threads) have had complained about hydraulic lifter failure due to manufacturing quality. (Mild-moderate crane camshaft if that is a consideration) Respectfully request recommendations. THANK YOU!!!!!

is there a thumb rule or formula that dictates a good size runner or scaled guideline regarding engine displacement size, RPM, and efficiency? I don't think I would be able to use this in the near future but am very curious. I am sure if you are building an SBC, BBC, SBF, BBF, or maybe even...
