Thanks for helping out Andy and passing on the information and knowledge to those who are in need or just wanted to learn how to do it and that's is priceless as American made parts!

[@UnityMotorSportsGarage]

Thanks John! I can only keep what I have been freely given by giving it away... I've had great success in the past with Howard's cams and I love the fact of American made parts... Andy

Cool vid 👌🏼 Titanium Retainers & 10° locks is a must 🏁

[@UnityMotorSportsGarage]

Thanks my brother!! They are a work of art.. Greg Brown did a great job on them.. he has everyone covered from the hot rod crowd to hard core racers.. all in one casting! It won't be long now till we hit the Dyno! Andy

Gonna be a beast once its finished

[@UnityMotorSportsGarage]

Scott I sure hope so... It's going to look good at least..lol Andy

[@hoost3056]

Having monstrous heads with just enough cam timing to do the job is the key to longevity. The OEMs finally woke up about this and all the heads from them are legit race heads. Those Hammerhead Hemi heads are stunning, by the way.

[@UnityMotorSportsGarage]

Thanks... I can't wait to see how it does... Andy

[@hoost3056]

@@UnityMotorSportsGarage the specs on the mild cam look like it can rev to 8000+....are you gonna let it sing?

[@UnityMotorSportsGarage]

@@hoost3056 yes Sir!! Going full send.... We are figuring it will probably make peak power around 7000-7200 so we will see! It's going to be fun either way... Andy

Just installed a Howards camshaft in my Holden 253 v8, highly recommend.

Back around 2014 I had been using the other Big cam names and I had a few hyd. flat tappet cams go flat and I switched to Howards and never looked back... Thanks for Watching and please subscribe to follow along on the build! Andy

Those heads make me think of Chrysler hemi heads! And those jesel rockers look sweet it's a damn shame ya gotta cover those beauties up with valve covers

[@UnityMotorSportsGarage]

The Valve Covers will more than make up for it!

Nice! Cant wait to see them!

[@Lagrange1186]

This build has got me on the edge of my seat! Love the updates and the info shared. If all goes well, any chance you might try and take Casper to drag week this year? Would love to see this build in person!

[@UnityMotorSportsGarage]

Thanks Brandon, I would love to give Drag Week ago, But it all depends on my transmission situation... Im going to start out with the C4 trans so I can do a comparison of Engine Dyno vs Chassis Dyno then its off to the track to see just how it all relates.. From there the plan is to install a Lenco ST1200 trans! Andy

[@biscuitboy3617]

Im really liking this project. What kind of power are you aiming for? Imagine this engine combo in a small, light weight car!

[@UnityMotorSportsGarage]

Thanks Biscuit Boy! The power goal is 750hp NA on 93 octane pump gas.... So we shall see! I would love to find a 70-71 Maverick to drop it in down the road to do a vintage ProStock build with it! Thanks for Watching and Stay Tuned! Andy

[@bcbloc02]

For those heads that seems like plenty of cam I would expect it to run well past a 7k rpm peak should you choose to rev it on out.

[@UnityMotorSportsGarage]

bcbloc02, I believe you are right.. when you have great head flow the cam doesnt need to be as big! I really believe it will peak at 7000-7200 rpm.. Time will tell... Theory to reality! Andy

[@johnparrish9215]

Andy, that is Cylinder Head Porn right there. It's looking better than a Vegas Show Girl...LOL

[@AryDontSurf]

I'm catching up on videos for 4/29 day. The neighbor here saw me working out back and asked me to get his 66 Mustang running. It's been sitting for god knows how long, but she has a V8 (302?) And I'll be damned if I don't try to get her moving.

[@ScottKenny1978]

What does the really long rocker arm on the exhaust side do to your valvetrain loads? I'm expecting that the cam is going to have a heck of a lot of force on the exhaust lobes...

[@UnityMotorSportsGarage]

Scott believe it or not, it is pretty stable! the only thing is the bit of extra weight on the valve side of rocker fulcrum.. which is why im running a bit extra of spring pressure... on a street motor with a solid roller I try to run 220lbs on the seat and about 550 over the nose... If the cam profile will allow me to do it.. That is why im running 240/625 on this motor Greg Brown has run this same rocker arm setup past 9000 rpm with issues... That gives me comfort as well... Andy

[@billsmopars4927]

Great video. Off topic question, I know you work with David Vizard...I have a chance to buy an old Superflow 110 manual bench for $975, it maxes out at 110 CFM at 10" water. Is it feasible to convert it to a full fledged bench with, say 400 CFM at 28" water? Or should I try an build my own? Thanks.

[@UnityMotorSportsGarage]

I will ask David... And get his input. Andy

How many more sleeps to the next vid Andy?

Hopefully I will get it up in the later part of next week! Its moving along pretty good now... Andy

These heads are all great and everything but what happens when your Hemi sb Ford starts kicking band X's (GM"s) butt on a regular basis? You get protested and outlawed by the competition. Ford has run into this before with the sb. Remember the Gurney Westlake heads used in the Ford Indy engines. How about the Cleveland/Yates heads, restricted by NASCAR and punished by the NHRA with weight rules. Aftermarket can build all the great heads to beat the General but the millions of racers running Chevy will protest these heads to oblivion. The same thing happened with the Ford 427 SOCH cammer, banned by NASCAR and restricted by NHRA so they can't compete with Chevy. I like all these great Ford world-beater engines but to compete with the General you need to build a better engine available to everybody, Ford is too late to the party for pushrod engines but the Coyote engine is kicking the General's butt every day.

[@UnityMotorSportsGarage]

It always happens...LOL Im just building this for Street/Strip action... Thanks for Watching RD Andy
