Any idea on the Engine Oil Temps ? Did they climb during the Dyno runs ?

Most definitely always give them what they want.... as long as adults are in the room and everything is up front ? NO problem ! Congrats and Good for him ! My only question is regarding what's 'special' here... about a 4 Lobe High Helix Magnuson 2650 Screw Blower/ Boosted 535 cubic inch at...

Forgive me here..... but I just don't get what's so special about that ? Don't get me wrong, nice engine and it seems to run well.... But that said.... I mean it is a BLOWN 535 Cubic Inch utilizing a Magnuson High Helix 4 Lobe 2650 Blower ? Plenty of guys have been making waaay more power than...

Agreed, If you go the 512 route the Stealth's are IMO, out of their league in any reworked incarnation. Being up in Canada we used to charge $1,000 CAD(about $750 USD) for what we called a "Street Port" on new OOTB Stealth's.... Ported all the way through/pushrod pinch etc and with redone Seat...

IMO, everything else equal, any hp gains TF Vrs Stealth should be proportional to the "average" flow increases the Engine can utilize ? My best guess from your info might be 25-30 hp peak with average hp gains obviously lower. IMO, when making a comparison such as this it's important to remember...

Depends upon the Bearing 'eccentricity' now doesn't it ? and how much time does it spend and how COLD really ? P Bearings can exhibit .0045" to sometimes as much as .0065" Clearance over closer to the parting lines depending upon the 'crush' applied during Housing Sizing. H's and V's...

If you want opinions about Oil Pressure ? Understand that Oil Pressure in any Engine is "relative" and is generally speaking affected by : * Bearing Clearances present * Oil/Operating Temperature * Oil Weight and to some extent whether it's a Std or High Volume Oil Pump once either hits it's...

You can get the Street Dominators quite close to Max Wedge sizing to retain good underhood clearance on an RB..... the trick for us has been to get the 'volume' back a good 3-4 inches up into and transitioning the runner.

We use the factory retainers, stock neoprene seals in the Kits..... never an issue. We 'hang' every BB Mopar engine we assemble here with just the Crank/Seal installed and completely submerged in Oil for a few hours before proceeding with the rest of the assembly. If it's gonna leak ?.... we...

Yep.... we 'hang' every BB Mopar engine we assemble here with just the Crank/Seal installed and completely submerged in Oil for a few hours before proceeding with the rest of the assembly. If it's gonna leak ?.... we want to know BEFORE we run it on the Dyno ! Forget the side seals, we use the...

For factory HP Exhaust Manifolds and the factory 4 holer '2178' 68/69 Intake/800 AVS Crower HDP271.... or the SUMMIT K6400 works pretty darn fine as well ! You could even get the Comp XE268H ground on 114 lsa and Nitrided ? Headers: you can use the stock CompCams XE268H on the offered 110 lsa

Nope..... only it's an Auto with "A/C" ? https://www.hemmings.com/partslocator/carburetors.html My only point being is why would someone remove the HIGH cfm flowing original AVS Carb and install a 600 cfm AFB Carb ? and, maybe the OP can re-acquire that original Carb ? because rebuilt properly...

where is the 440 HP Engines original Carb ????????????????????? Because if it's a '68 "HP" 440 Engine ? they were already equipped from the factory with a larger Carter AVS Carb, which is already up around 730 cfm ? why would someone remove a High cfm Flow Carb and install a smaller 600 ? They...

The 2 BBL Cam doesn't have sufficient Lift nor Duration to take advantage of the added Airflow the 4 BBL Intake provides.... forget it ! Placing a 4 BBL Intake on a 2BBL Cammed Engine was/is and will always be a waste of time, except for 'appearances' which is all anyone ever gets. All you did...

What were the V/Spring Pressures used here ? We run it LOTS of Comp Cams here.... never a problem ? So I gotta ask things like WTF kind of V/Spring Pressures are people trying to run these Flat Tappet Cams in on ? Doesn't matter if you use good Oil with Zinc and then trying running a Flat...

I hesitate getting involved because most of the time nobody listens anyways ? just say'in.... it's OK to ignore this post and carry on as you see fit, I won't take offense. That said, What Cam ? What Rockers ? and Ratio ? You need 125-130# seat pressure..... anything much above 300# @ .500"...

Question : Did you remember to machine a 2nd Keyway in the Crank Snout ? Just say'in.... it's not "if".... but "when" that stock Keyway if it's all by itself..... will just shear off trying to turn that Blower PS: and remember to use a Steel Scattershield with that 4 Spd behind a Blower if you...

Neither.... Consider using 3/4 Groove Sealed Power 119M available in std or .010" under

Piston selection is absolutely critical with 440's in regards to the 'compression distance' of the Piston, and probably one of the first areas to consider adding to the Budget. Do NOT accept Pistons spec'd in the low 1.9's Compression Distance range, with even the 1.99" offerings extremely...

A few questions if you don't mind. Rotating Assembly Oil 'throw off' is an integral component to Cam/Lifter Oiling in these engines.... and the unimpeded flow of Oil is also critical to Bearing and Engine Temps in Performance applications What Bearing Clearances are in the Engine that you are...
