not knowing your cam specs and valve spring psi's and rates, I would suggest you determine if the roller rockers are necessary, if not I would use factory rockers before screwing up valvetrain geometry.

Dan, summit part # crn-15634-16 available @ $135.99. 3/8 hardened 8.786 int., 9.142 exh., I know we talked earlier today so this is for anyone else reading this. The trick is 90 degrees at 1/2 lift.

i would guess the dist is 180 off. when you check TDC are you pulling #1 plug to make sure your on compression stroke? with rotor pointing to #1 on cap, if points style dist. and timing mark at 0 or I prefer to static time and have the timing mark at 4-6 BTDC, rotate the dist housing until the...

cylinder cases vary in thickness due to core shift, etc... if you want to know how far your cylinders can safely be overbored than have the walls sonic checked, the machine shop will then advise you of your options.

1911 good guess, shooter, ipsc etc... licensed gunsmith when time allows, certified instructor, blah blah.

hand etching the numbers is common practice, & that was the info we needed. check for a PM from me. crewchief

283/327 used a road draft crankcase vent, your dad is correct, you need covers for a PCV system. Positive crankcase ventilation is what it means. I would still check to make sure that the timing marks are accurate, etc... The 3970010 block was used for many years {69-80} and could be 2 bolt or 4...

Chevy made both left and right dipstick blocks, I would suggest buying a new pan and timing cover and an 8" balancer. The pan you need depends on where the dipstick is. You may need a new dipstick and tube. '68 and earlier balancers timing marks are retarded 8 degrees compared to the 69 and...

Fran, the biggest problem with the 400 was the cyl. heads. 170 cc intake runner volume is great for a 302 a little small for a 350 and junk for a 400. 200 cc's is the min. and that only for a tow veh. or mild street / strip. Change your heads to the dart 200 cc sportsman or larger and along with...

we returned all GM crate replacement engines for core refund, I refer to the "target" engines rebuilt by or for GM. This was true 1980 thru 1996. Partial & fitted blocks as well as over the counter performance engines did not at that time require an exchange. If the price quote was for a target...

Fran, you gave good advice, sometimes I forget that things are cheaper for me. Something I would like to add is it seems to me odd that every engine I've seen sold at a junk yard had about 70k according to them, regardless of what a teardown reveals. I would feel more comfortable with the used...

spoken like a true 409 ahhhhh enthusiast. sorry 409's were something which I would pass on in my youth as mark IV's were more in my price range and parts were more plentiful. That said I kick myself every day for passing on 2 409's at a local bone yard when I was 16, but who knew, muscle cars...

Not knowing what Fran's down & dirty method is, I'll say that every engine I've ever encountered that was rebuilt by a novice alone exhibited major problems. The root of these problems was always the lack of knowledge required to identify a problem and what would be the correct repair. The...

I thought we were friends, I see no need to get evil.

sounds like a good plan. I couldn't get to sleep thinking about this so before anyone calls me on playing fast and loose with my terms, I choose the word oversized carefully because it didn't look like you understood that the hole in the assembled rod and bearing gets smaller as you increase the...
