Is the only reason you need different head bolts is because the magnum uses different bolts? Basically can you use stock Magnum bolts? Or is there actually a special bolt set?

Anyone have a recommendation for a valve spring that works on a magnum head with factory head going on a LA block with a hyd flat tappet? I see the Hughes 1110, they have 120# on the seat which to me seems just a touch high, would be nice to find a +.050 retainer as my math says that would...

any particular gaskets y’all are using with your trick flow heads and headers? Or any specific ones to avoid?

Looking at hopping up my truck that is a 92 with a 5.2 magnum. Debating how much I want to try and up this thing and where the giant leaps in money are needed. So curious what are the limitations of the factory keg intake, injectors, and PCM.

So I get in the habit of collecting parts I want, then they sit, then I get sick of looking at them so that's when I usually end up building something. So I started building this 360 to clean up some projects and I was working on it yesterday when it occurred to me that sans block and crank I...

Just wondering what kind of sonic numbers you've seen to safely bore a 318 out to. Ive heard some myths and whatnot, just wondering what kind of data you've collected. :thumbup:

.040 over 360 block with a 4" arm, 9:1 compression, MP .557 cam, 596 heads, Eddy air-gap intake, in a 3550 lb duster with 3.91s and a 3500 converter. had the cam in at 108 and it had 145 psi cranking. i advanced it to 104 and it now has 160. mind you i take my readings with the motor cold...

Considering building a 340. Block doesnt need to been line honed as it sits, and was wanting to stick with the factory style 2,4 bolts with provisions for windage tray but was debating studding 1,3,5. I know 2,3,4 take the majority of the load, so is it worth the $200 in line hone to stud...

So i was degreeing a camshaft last night; I go through the usual steps, TDC, Dot to Dot, etc. I check the cam via intake centerline method shooting for 106 to 110, and the results were......wait for it.........20! Yes, 20, not 120, 20! I could not believe how far off this was. My go to...

For a given motor, what kills them more; rpm or hp? Discuss

What are you guys running for seat/open pressures with your .557 cam. Also, what kind of RPM are you turning? Final question, do you think stock 915 J head valves will withstand the pressure or do I need to step up to aftermarket? :thumblef:

I have a .030 over 340 block that needs to be honed and a set of 2316 TRW forged pistons Id like to put in it. Whats the max piston to wall clearance you guys recommend or have run with this type of setup? These are the older pistons and this is a budget build so trying to avoid boring and...
