    Biggest mistake ever- lunati cams

    Biggest pain in the *** for this build is what I meant. I too had a woman ruin my life but she also gave me 2 children which are also the best part of it. Personally, I stated that I bought this cam profile to use power brakes along with performance aspects for the street and could have got a...

    Biggest mistake ever- lunati cams

    Distributor should be on # 1 after intake closes and the mark comes up because that is it's compression stroke then fires at that point. Unless I am mistaken.

    Awesome knowledge. Really appreciate learning that. I have a good 10-15 rebuilds under my belt over the years. Just turned 60 yrs young last year and just finding that out makes me more wise. Thanks again!

    Wow. I never knew that. That just made my brain smoke! Lol Totally makes sense now. Just never thought of setting it up like that. Then just check with a light to dial it in. Most are saying 35° with that cam but don't really need that much to start with.

    My damper has up to 60° marked and also grooved every 1/4 turn. So I just spin the crank till say 30° on the damper and line up the cap/rotor?

    Agreed. Still a lot of $$$ tho. Better safe and good knowledge helps a lot. I only know enough to be dangerous so every little bit of info helps. Also a #s matching motor so a little more stress for me.

    Once the intake opens and the piston comes up, that's when it is tdc correct? How do you figure out the 30° with rotating the distributor? Also will that be clockwise or counterclockwise? I always just lined up the cap with the rotor, fired and set the rpm then grabbed the timing light. If there...

    Biggest mistake ever- lunati cams

    Well between this and the e body site, I got the information I was looking for. I also got some informative videos which pushed me to making a smart decision. I decided to remove the inner springs for cam break in just to give the cam it's best chance to survive. Spring psi is set and I am...

    Biggest mistake ever- lunati cams

    I loved the purple shafts. I had a motor built by jegs 45 yrs ago by jegs and the stuck a racer brown cam in there. That was an awesome cam and recently built another 340 with those same specs. I called him at racer brown, as the original owner passed on. Was a lil difficult to get a hold of...

    Biggest mistake ever- lunati cams

    My intentions were fully explained to the shop before the work was done. I had them shaved to 63cc to have the compression where I wanted. I also had the pockets matched and seats re cut for 3angles. Gave him the cam chart and told him that I needed the springs installed. A few weeks later, I...

    Biggest mistake ever- lunati cams

    I was able to use the springs that were spec'd for the cam. When I bought the PKG, I called lunati and talked about it with them before I bought it and there was no issues getting in touch. That was about 3 years ago. During the build, I heard about the sm heads and decided to go with them so I...

    Biggest mistake ever- lunati cams

    Agreed. Was overheating on lunati mainly because of their horrible tech line and the machine shop that was paid to do the work was a highly recommended shop that plain just screwed me. If I would have known that I could shim that much I was able to handle that. Even still, when I took the heads...

    Biggest mistake ever- lunati cams

    Took the sm heads to a machine shop which was hard to find during the pandemic, still in the boxes to be checked and set up for my new cam choice. Paid them 1100$ to assure they were set up properly. Stock heads were worked before that by same shop. I explained that I wanted to use the lunati...

    My neighbor build motors for sprint cars and put that same cam in a Chevy for his son with both springs installed and it runs great. The machinst builds lots of motors with lunati cams He used to build motors for Mike Dunn before he went into nhra. He said it's a waste of time and I realize that...

    Biggest mistake ever- lunati cams

    I started this thread about lunati's horrible tech, and pairing the speedmaster 3048 heads. Problem was installed spring height was way off. With these aluminum heads, it was way off. .110-.120. The spring pockets need a steel seat and they can be shimmed. It should be done by the machine shop...

    Biggest mistake ever- lunati cams

    I have acquired a lot of yes and no with the dual springs but my issue was spring pressure and not really breaking in a motor i got a lot of both yes and no. . Once the springs are set within the suggested pressure, then I decided that 115/336lb isnt worth leaving the 2nd spring out during my...

    Biggest mistake ever- lunati cams

    Well, I definitely made the issue way harder than needed be. Took the heads of and to another performance machine shop nearby and he took the measurements and popped two .060 hp shims in the spring pockets and got my installed height down to 1.710. The springs were showing 125lb but will relax...

    Definitely was in this build. If I would have known the spring height was different, I would have tried to figure it out. Last minute change so I went with the flow. The machine shop was aware of the cam being used and the stock heads were a good fit for the springs but in all the swap, I didn't...

    What springs did you use? What was the installed height, bind and seat loads? I think speed master is a Chinese version of Edelbrock.

    Biggest mistake ever- lunati cams

    Yea, the machine shop swapped them over like I asked but never checked anything. That's what I get for trying to use aftermarket crap.

    Biggest mistake ever- lunati cams

    Agreed on my mistake which started when I purchased the speed master heads. They went right to the machine shop where the stock heads were done and when I picked them up, I noticed that the lunati springs were still on the stock heads and I told them that I needed them on the speed masters. Well...

    Biggest mistake ever- lunati cams

    I think comp and lunati are the same because my machine shop told me to call them to see about a fit for the spudmasters and the same damn music and message on hold. Exactly the same. 1 hr 45 minutes yesterday afternoon, down to 2 callers left in que and they closed. Please call back tomorrow...

    Biggest mistake ever- lunati cams

    Well 1st off, lunati tech support really sucks. 2hrs 45 minutes and got hung up on. My issue was my mistake tho. I ordered the voodoo cam/lifter and spring PKG. Cam # 10200703. Spring # 73195k which was fine and dandy for stock x head spring height however, I got the speed master heads bug from...

    Speed master spring issues.

    My concern was that the length between the seat and retainer was longer than a stock head. Probably about a 1/2". I have tested spring psi before and after all the head work, the shop had reinstalled the original springs that the heads came with. I explained that I bought springs along with the...

    Speed master spring issues.

    I got a set of the aluminum heads and had them reworked to assure they were good to go. Recut, port matched etc.. My problem is I decided to use the lunati voodoo 703 cam and bought the recommended springs for the cam but when I went to change the springs over, I noticed they are not the same...

    If the timing chain is bad, you can change it in the car. Just remove fan-radiator-alternator-damper-timing chain cover.

    Question about the speedmaster heads.

    Thanks for the info. Much appreciated!

    Question about the speedmaster heads.

    I want to buy a set of these for my 340 e body and need to know something about the exhaust ports are raised. Will that cause any interference with the dougs d453 headers? Also, do they have hardened seats for unleaded? Main reason thst I want them.

    Mopar performance alternator 1or 2 wire???

    The car has the later style VR with a green and blue wire. Mancini stated to just bypass the VR and it will work since it has an internal regulator. Do you think that would cause any issues? I am not running any ele fans/ pump etc. Maybe an amplifier for a stereo but thats about it other than...
