L24 Engine Build, Head / Camshaft Suggestions
madkaw replied to ksmithgall's topic in Engine & Drivetrain
You want to stay internally oiled . No difference in metallurgy . Get a good big cam and have fun -
L24 Engine Build, Head / Camshaft Suggestions
madkaw replied to ksmithgall's topic in Engine & Drivetrain
I don’t understand the cam oiling issue ? You should be able to re-grind the cam that was in it . -
Appreciate any insight
-
I called , but they are out of the shop until the end of the month
-
Anyone with recommendations where or who to send bumpers to for restore . Customer has a very clean set that are super straight with just mild surface rust . This will be expensive either way , so I want it done right . Like to hear actual customer reviews if possible . thanks

Pics?
-
How’s my header coming along !!!!!

So you have valve timing marks that show excessive slack. You have a poor running motor . Now you have valve train noise . Time to pull the timing cover
-
Art and function done well . I still admire your skills . It’s hard to watch without being envious of your meticulousness . Fortunately I have a friend with a mill that can make me precision , because I’m more the ‘get er done’ guy .
-
I believe this was mentioned by someone else in this thread . I decided not to use their supplied nut for that reason of seizing
-
The timing curve is not going to adversely affect his troubleshooting
-
Very similar but has square exhausts instead our U.S.A. round ports
-
It would be nice to swap out with a known good dizzy . Maybe the shop fried your ignition when they installed it . Did it run okay after they put the Pertroni in?
-
Not enough history here . Did this motor ever run right ? Did this happen only after the carb work ?
-
Need more background info . Did you rebuild the engine ? Did it run right previously?
-
Ignore the bright link . That dizzy spline should be at 11:25 o’clock . Looks like yours is at 12 noon .
-
I don’t know guys - looks like that dizzy drive shaft is off a tooth if that’s TDC .
-
You guys haven’t even mentioned the best head yet - MN -47 . Because it wasn’t in the Z , people forget about it . It has the best all around combination for a street motor . Maybe not the best race head , but best bolt on for power with the least amount of work . Small chamber - high quench , good casting .

Going thru this dilemma right now with my current customer . Needed to spray the engine bay . His is a 2/72 . I thought 918 was the only orange , but when the painter mixed it he said it wasn’t even close . Too light of a color . He took the gas door in and matched it . The paint shop called it code 56? It looks Very close to Hemi orange . Was there two different orange colors ? Same dilemma with interior color . White or is it off white ? I will add that this car was re-sprayed at one time .

Get a vacuum gauge and plug it in somewhere it sees full vacuum . You should be 15-20 hg at idle . Closed throttle will give funky compression readings
-
Sounding like a vacuum leak . You need to spray something around that gasket while running . That would answer why you need some many turns out if you are sucking extra air . The wrong impedance on your coil would answer the sooty plugs . Pull a plug out with the wire attached and turn over the motor - preferably in low lighting - and see if the spark is blue or more yellow . Don’t worry about the cam sprocket for now - get the basics first
-
When you checked the mark on the cam sprocket at TDC - was the #1 mark on the sprocket where it should be ? Id say your valve timing is retarded by the pic , but doesn’t explain running issues . Don’t be shy about advancing the sprocket - it will help low end torque . 4.5 turns seems way too much . Sure you have the needle jets seated correctly ? Verified good strong spark from the plugs ? Verified no vacuum leaks ? Taken a vacuum reading ? Compression test ? Was Pertronix set up properly based on ballast resistor used or not ?

That’s a 2.4 with 3.90’s . Makes a huge difference in performance . I think biasing to a shorter gear is your best bet for overall fun , unless it’s just going to be a highway queen
-
I’ve have the 3.90 . I had it with my 2.4 and my 3.2 , it just works well. I originally had the T-5 which is a bit of a wide ratio, but it made for a great passing gear in third . If your engine made power all the way to 7k , then you had a hell of a passing gear . Anyone hear third ? Im not much of a high speed guy, rather just be quick . Like said above , what meets your driving criteria . Don’t do a lot of highway cruising and wouldnt be afraid do hum along at 3500 rpms either . 825E8147-CCCE-4270-8C19-819A0CFD87CD.MOV

I have that adapter that I will never use if you need one . I couldn’t use the RB flywheel
