Going .070" over shouldn't be a problem if you need to, most all 454 blocks will go clear to .100" over without a problem, it is taking them .125" over that it starts to get really risky.
I wouldn't get all tied up in a knot if .060" won't do it.

The .070" over pistons are pretty common size too.

Depending on what they tell me afterwards, I may just have them sleeve that hole if it's rediculous what's going on.

While I'm waiting on the machine shop(hopefully be this week they tell me what I need to get a rotating assembly in.) I'm thinking instead of heads first, I go ahead and get cam and lifters, this will let me get an oil pan and timing cover on to seal the short block.

So, it looks like the moroso 20408 pan is what I need with the dimples in it for steering. For oil pump, I'm thinking the melling m77, any issues here? And I'll get the biggest pickup tube I can, couldn't hurt, right? How much gap between pickup and pan do I need, have plenty of play dough to set the gap.

What's a good timing cover that isn't rediculous $ and any issues with a gen VI timing set? More below on that.


Now for the fun part where fights break out,lol. I'll start with saying I'm going with a step nose cam so I can use the retaing plate and gen VI timing set, any issues with the Chevrolet performance kit(plate, bolts, single roller timing chain and sprockets.) I'm going to use short water pump and accessories so I'm not so tight on fan clearance. Using a lincoln MKVIII electric fan currently and will keep it, works awesome on the 455 Buick. So it should work on the 496.

Here we go, what would be the recommendation on a cam,hydraulic roller, nothing else. Compression should land around 10.4-1, give or a take a tenth. Car runs around 2400rpms at 60mph now, 3.08 rear gear, 215/65/15 tires, roughly 26" tall tire. Need vacuum for brakes is about the only hinderance I can think of from jurassic size lobes. I'm after performance first, idle sound is a distant afterthought, it's a bbc, it'll sound good anyway, lol. Oh, gonna use Brodix race rite oval port heads just as a reminder. Intake and carb, I'll pick your brains later.
Or, since I'm a 30 minute drive from Straub Technologies, just go to him and avoid the fight altogether.


I have seen the Howards lifters for $375ish a set and Morels are around $425ish a set, one better than the other or is it a wash? Don't even bother with the knockoff $160 crap lifters, not wasting my time on that.

Well, there's the skinny so far.

Got the call this morning, she'll be a 496, .060 over took care of it. Everything else staying standard size, just cleaned up. Ordered rotating assembly from skip white, said should take a week as I'm waiting my turn for balancing.

Well, got a call at 0700 this morning asking which flex plate I want and he would have it he rotating assembly balanced and rods sized by this afternoon. Got the 168 tooth flex plate btw.

Picked it up and dropped everything off at the machine shop, machinist wants the cam and lifters to set that up properly. So, ordered a Howard's p/n 122116-12 gen vi cam, plus gm performance parts timing set with retainer plate and will drop those off when they show up.

Here’s what made it home with me. Didn’t have time to snap anything of the rotating assembly.

Alright fellas, question time, but first.

Cam, lifters, and timing set will be dropped off in the morning, then the short block comes back to me.

Question #1, what oil pump should I use, my gut feeling is Melling m77, just standard volume and pressure. Oil pan will be moroso 20408 and pickup to match.

#2, what brand torque converter do you guys like? I want to buy one and be done.

Thanks in advance.

Wow, I had to go back and look up what that cam is...it's really mild, rpm range 1800-5600 and that's in a 454, in a 496 that's going to drop to 1500-5100 rpm.

Converter - Performance Automatic(PA), FTI, Freakshow Performance, Coan, Ultimate. I would guess around 2400 stall, and it'll be a tire shredder for sure at 496" with that cam.

Yeah, standard volume pump unless you have main and rod bearing clearances on the wide side(.003"+)

Didn't figure on that drastic a drop in rpm range, not the end of the world if it is. I did get a cast crank after all.


Thanks for the tc company recommendations, I'll check them out.

Melling 77 is fine with me. If you get a little itch, it comes with a "corvette spring" that adds almost 10psi. May need oil drippers in the valve covers for it. Still it's lower psi than their high pressure pump.

M77 is fine for this engine.
I like the cam for a driver, will have almost smooth idle. Get 1.8 rockers, the heads can make use of the extra lift.

I'll for sure be using baffled valve covers, oil is expensive enough without greasing the intake.

Good deal on the oil pump. I did buy the tougher driveshaft just in case, but that was more of a while I'm at it thing.

I'm not gonna drag race and AA dragster idle wasn't my concern at all for picking that cam, I like drivability and where will I spend most of my time, around 2000-3000rpms, and the Howard's fits right in there.

I'll have to behave for a while till the transmission is beefed up and I get the 9" installed, pretty sure the 8.2" 10 bolt will scatter if I floor it, even with 215/65/15's. Plan here is rebuild for 700hp(way overkill I know) the th400, and a 9" with 35 spline minimum axles and 1350 u joints. But, I'll just use the widest tires I can fit in the wheel wells, don't want to butcher the back end.

You can get a 275/60/15 under the back with a 8" wheel 4.5" backspace, 8.5" wheel 4.875" backspace, or 9" wheel 5.5" backspace.
