This is a situation that MANY people find themselves in. Build a gnarly engine with all sorts of fancy high-performance parts and put it into a street car, only to realize that they'd enjoy the car more if the engine was less extreme. When you're in the planning stages of a project, it's hard to not be lured into the more, more, more trap.

Good on ya for admitting to yourself that you weren't completely happy with the engine configuration. I bet you'll be a lot happier with a more toned down mill.

Thank you for the compliment. As far as the engine goes it was great. A damn powerhouse that was just an amazing performer. I was driving it everyday and if you were so inclined it would be easy to do that, but….it was a handful. It wasn’t a car that you could just punch from a stop, hell at a 60 mph roll it would just fry them if you dropped down and nailed it. If you want a car you can drive on pump gas around town AND stomp the hell out of your class at the track with a set of slicks this is the cam for you. I am keeping the specs. Paul gave me exactly what I asked for.

This is the eternal struggle for many. For a daily driver type vehicle 500 Hp is more than enough in my opinion. For a weekend beast the sky is the limit.

First off very sorry to hear about the engine.

For all the neg comments about roller cams, I love mine too. More vacuum, more power, better idle in my case, so I know how you feel about wanting to save the cam.

What is your exhaust setup? I know I hated mine on my Bird. Went from a strait through design to a chambered designed to the Dynomax VT before I was happy with it. Even is you loose a few HP it may be worth your sanity.

The UD 288/296 even on a 108 LS ran A/C fine in my RAIV 400. I'd put it on a 112 though. Has the same 0.050 as the RAIV but shorter seat duration so a little better idle I think.

I called Bullet cams and the guy I spoke with spoke very monotone in a bunch of terms I did not understand and left me more confused than when I called. I read him your exact post and he just kept on going without ever missing a beat.

So looking at their lobe chart the H5 288 231@ 0.050, 143 @.200
H15 296 239 @ 0.050 151 @ .200 look like the lobes. I have a cam card I can look at tonight. I'd put it on a 110 or 112 to tone it down a little at idle. Butler used to sell them on 110s. I used on on a 108 in a 455 and the 400 shortblocks with my RAIV heads. I think Lee Atkinson also had one on a 108 in his first gen Firebird and a 455 for years.

My 455 RAIV weighing 3900lbs (had A/C and iron heads vs E heads and no compressor/condensor) in my TA ran 12 teens @117 with 3.42 gears and road race suspension

Very same cam through lunati. Claims to be in stock and probably much cheaper price.https://www.lunatipower.com/street-s...8-288-296.html

Harold from UD worked at Lunati after he shut UD down because of IRS problems, they have the UD lobes also although when there their IC is not as advanced as he would do at UD. Then Bullet also got his lobes after he left Lunati. The 296/304 in my TA was when he was at Lunati.

Sounds like a typical response for a 25 year old. Most of us would have felt the same way at that age, myself included. I bet in 20 years he'll understand why toning things down is the better choice for the application.

Tell the nephew you'll build back the same way if he agrees to split the maintenance costs with you. That might inspre some critical thinking lol! When I was a 25 y/o we chose our cams by going down the description list until it said "rough idle" so I get the youthful exuberance and all.

As I said earlier, a car made to be driven has to make compromises to maximum power output. The only one you're going to beat is yourself when it breaks. You want the reliability to set it and forget it, change oil and filters and enjoy it, not sit in a car worrying about every little tick you hear in valvetrain being the last sound you'll hear.

Any cam over 230 degrees .050 duration is going to turn heads and sound badass through 3" exhaust. My Crane HMV 234/242 installed at 108 sounds pretty radical through a 2-1/2" exhaust. Everyone who hears it thinks it's more radical than it really is. Here is a short vid. The idle gets loopier when in gear, of course. Any RA IV style cam is going to sound like that.

https://youtu.be/jy2-6x7sJR8

Early on, you mentioned you bought a Refurb MSD Streetfire box but mentioned later that your Summit Box had no rev limiter. Why'd you ditch the Streetfire that had a rev limiter built-in? The refurb Streetfire box w. rev limiter is $110 w free ship from MSD when they have them. I bought one just to have a backup to my 30 year old MSD 6 box and installed 6 pin Duetsch connectors so I can "hot swap" if needed. It's cheap peace of mind.

I ditched it cause I’m a dumbass and allocated funds to other areas of the build.

The RAIV cam or equivalent would be the smallest flat tappet hydraulic cam I’d consider using. But it really wouldn’t be my pick especially for a stick shift car.

This 296/304 Ultradyne looks good 239/247 @ .050 .507/.530 with 1.5:1 rockers. I’d use 1.65 rockers to bump up the lift to try to take advantage of the good heads you have.

https://www.lunatipower.com/street-s...8-296-304.html

Just my amateur choice, it wouldn’t hurt to contact Paul K or another expert for his pick within your flat tappet budget constraints and aiming towards something that doesn’t require messing around with after you seal up the valve covers.

Roller cams aren’t for everyone. If you’re not into staying on top of them, doing the lash and necessary inspection I wouldn’t run one.

If you want the performance of a roller cam you can get with reliability. It will cost you and you need to have a proper custom ground mechanical solid roller cam ground.
The BAM lifters with the DLC option are 1000$. You will not have your lash moving around. If 1000+ HP naturally aspirated engines run them, 2000+ HP twin turbo engines run them with their required valve spring pressure a little custom SR will not touch them.
Its expensive but its the answer to all these hyd roller lifter failing and ruining engines.
Maybe Crane will start making their fine hyd roller lifter again that would be a big help too but even they were over 700$ when they stopped making them.
If you are going to run a flat tappet do not waste your time with a hyd cam. Get a custom sft. They are not a big maintenance item like some people think. As long as you have a nice set of roller rockers with USA made poly locks your engine will not be any different than the millions of sft 4-5 and 6 cylinder engines in service today.
You can run a stud girdle and that gives another layer of protection from things loosening up if you want.

After consulting everyone and their momma on here and calling every cam company that was open on Labor Day weekend I decided that too little was better than too much. I ordered the Crower 60919 from Summit. I called butler and got setup with a package for all the other valvetrain stuff I will need. They had my previous order info and knew exactly what springs, pushrods, lifters, etc to order.

Great that made your life allot easier for you. Trust me you’ll be a happy camper, I think you’ll be very surprised. Plus you’ll still be able to smoke those tires
