Rebuilding your own engine can be fun, rewarding, and expensive. If you just want to 'get er done', you can buy a crate engine, with a warranty, for about the same price: http://www.summitracing.com/parts/MLL-BPC4082CTC/

Somebody forgot to torque down the hooter valve: LiveLeak.com - Dyno disaster.

If you want to spend a few extra bucks and take the crate motor shortcut, it's worth it. I build my engines because I enjoy it, but sometimes you just want to get'er done. If I were you, and that's the mood I was in, I would: - Purchase a Jeggs crate motor for $3600...

Is it just me, or is there something wrong with the valve keeper in the RHS photo?

I would splurge and get an overdrive transmission installed. You can do almost anything you want with the engine and final driver ratio and still get great gas mileage compared to any non O/D transmission.

"PM me for moral support and free parts".... I LOVE this place.

My friend had a 408 with RHS heads built recently and the builder tried all sorts of rocker gear, finally decided that the Indy rocker arms were the only ones he could achieve the proper geometry with. I think the rocker set cost him $497.

You lucky guy, all I get from my wife is taken out for dinner for my birthday. Very nice, keep the pictures coming. Kenny Kevko said they fit.... I haven't tried yet, but I suppose they will.

I suppose she thought in the long run it was cheaper than being our drinking and carousing. Smart.

It's a 408 stroker. Dyno'd at 457hp/508tq. Details here: http://www.forabodiesonly.com/mopar/showthread.php?t=170325 It's getting FAST EZ-EFI. The dyno numbers were with the dyno 750 Holley and headers. That's my bud Max's Silver Cuda, he's a member here too. He stroked a 360 to 408 with...

Whoooohooooooo!!!

Yep, we dynod mine at 32 then moved it to 34 with no improvement, so moved it back to 32.

Eagle stroker kit with crank, rods, pistons, bushings $1250, plus machine work, heads, cam, gaskets, headers, EFI setup, yada yada yada. I suppose I'll be $8500 in this when it's all over counting the heads, EFI, and TTI headers. You could probably stroke a 360 on the cheap for around $2000 if...

Thanks for all the input. This is my first motor and it's been a great learning experience. I think I will use the cam as is. I'm going to stay with EZ-EFI for a few reasons: - Reliability (arguable if you're a great carb guy, I am not) - Engine longevity - Better cold starts - Better gas...

It ran fine with 93 octane on the dyno, hopefully will behave well on the road with 93. 93 is available just about everywhere in Dallas. I don't know why my (ex) engine buy went with higher compression. He said it would handle it with aluminum heads. Then again, he also selected a cam that...

Engine builder said I have 11:1 compression. I had it confused with my buddy's RHS build compression.

I'm pretty sure I saw a Schoenfeld tag on the headers.

My Mopar bud Max ran his engine the same day. Same engine, cam, pistons, intake, oil pan, but he has a Mopar cast crank, stock 360 rods (narrowed) and RHS closed chamber LA X heads with 1.92/1.60 no mods. Same dyno, he pulled 425HP and 475 torque. We were expecting his motor to pull more than...

Here's a picture of the cam card... I suppose I might have left some horsepower on the table, as you say. With a 3000lb weekend cruiser I'm not too concerned about it. I'm really wanting good drivability and street manors.

Finally spent some time at the dyno... for anyone interested, here are the specs/numbers: 1973 LA 360 block, .030 over Eagle cast crank, 4" stroke Eagle I-Beam rods Mahle stroker pistons, coated, 447g, flat top Compression 9.8:1 Heads Edelbrock closed chamber 65cc, mild port matching Cam - I...

Okay, looking allpar.com says the 360 was produced from 1971-2002. How to explain a set of 'Z' heads, casting number 3418915B (missing the 5 in some places!?!), also has the AAWJ360, but with a production date code of 10139? Isn't that Oct 13th, 1969? I just had these reworked, but before...

And 'the solution to pollution is dilution'... if you got into the motor at a good price, why not spend $1200 and drop an eagle stroker kit in it. 408 torque monstor. About the same HP and torque as a factory 426 hemi in the day, hundreds of pounds lighter.

Grab a copy of 'How to build Big-Inch Mopar Small Blocks" from amazon.com. they have 6 or 8 sample builds in the back of the book using a variety of carbs, cams, pistons, compression, etc and have dyno reports for most of them. Very informative.

I agree, the installed valve height has to be identical on these mopar heads due to the stationary rocker shaft configuration. You only have a couple of options to change the valve geometry on these heads. You can either raise or lower the valve stem height (grind the valve stem to shorten...
