Pete, going to a roller is going to cost you $1,000. Even going to a solid flat tappet will be an extra $80 for pushrods... If you plan to keep the power brakes, I wouldnt recommend anything bigger than say 240 @ .050 with a hydraulic and 245ish with a solid. Thats the ragid edge. And nothing tighter than 108 or so on the LSA either.
IMO, with a street type application (6000 rpm or so), a good newer design hydraulic cam is going to make within 10-15 horsepower of a solid cam of similar rpm range. An apples to apples comparison years ago with my car showed a 12.19 @ 114 with the 3844 Hughes hydro and a 12.08 with the 4550 solid..
Ok, the $1k is close to what I remembered when I decided to buy the Ebrocks. It was either the Ebrocks or the roller cam, and I opted for the heads with more potential. It was the right choice for my purposes.
I don't have power brakes, so that's not an issue. Front disc/rear drum. Does that influence a reccomendation at all?
The lower I can shift, the better

I edited my above post to show you the new hydraulic cam by Hughes. Take a look at what they have. As far as the power brakes thing goes, and for my recommendation, no it doesn't change much. There are ALOT of guys that are much better at this than me. I'm just thinking about your current converter, gearing, and the fact that you drive your car so much. All this talk about how the difference between a 360 and a 408 is night and day, well I can tell you this. 340's do not make anywhere near the torque that a 360 does. Now go from 340 to a 414 and you are in for some serious attitude change there buddy. I can only imagine what it would be like to air out such a car/engine combo with 3.55 gears on the freeway.

Right, I don't want to redo the whole car, just use what I have and make the most of it. The engine will be redone simply because I dont know it is properly balanced, the pistons are cast (ugh!), it takes a bit of oil (no smoke) and I want to make sure it is done right. Who knows, maybe this 340 has the 4 middle rods installed with the chamfer/squirters on the wrong sides like my old one did 
BTW, the 3.55s on the highway are fun now - cant imagine what they would be like with more torque and hp

once you get in to the 240 @ .050 / .510" mark with some good flowing heads / exhaust / proper air-fuel, you will be near 500 HP and over 500 ft. lbs. of torque. 3.55's are a great gear ratio for this combo. And even better if you stuff a Keisler 5 speed in there down the road.

I put the roller bushing right in to my crank... No problem.. 5 speed is a big + but I'd take a 3 speed over an automatic any day.

This is a TON of great info. from all you guy's! THANKS!
I am in beginning stages of building a 4" stroker out of my 340 for my '70 Cuda.
I just called Mancini Racing and they tell me for street duty I will NOT need H-beam rods and Forged crank.
Are they just lining me up for their overstocked I-beamed/cast crank combo's or are they true?
He asked me if I plan to do track duty, i told him an occasional blast down the quarter, say once every 2 months on street tires.
How do I drive? I get on it HARD here and there, rolling burnouts once in awhile.
So do I need the H-beam rods? Or do I need at least a forged crank?
He suggested the same as you all did about balancing, external w/ a good balancer.
How about the cam? I know the duration in teh 240 range, but solid or hydraulic?
My 'Cuda I drive daily 8 miles to work, 4 speed (soon Keisler 5 speed) and has manual brakes, no power steering.
What rocker ratio?
What carb to go with?
I want deep 11's, so what specific cam should I go with?
Many thanks from Hawaii!!!
Gil
P.S. Edelbrock heads, TTI headers, Air gap intake are on the way.

I'm running a cast crank, my machinist says no problem, its a nice piece. I bought Scat H beams for 380 delivered. They were on the money, needing no further machine work, like Eagles usually do. I think they are the same rod (H beam), but the Scats are finished in the US. I am buying a solid roller set up (cam lifters, springs, pushrods) from Bullet Racing Cams, 800 for all, a very good price IMO. if you want to make big power, i feel a single plane is necesary, this isn't a 340 anymore, I am using a Strip Dom, the only single plane with the mounts for a/c. p/b, and plenty extra places for fittings. I'd go with a Demon carb or something like it, the driveablility is much better than stock Holleys. Other than that, go with the best parts you can afford, to avoid doing it again.

from what i understand,the eagle "i beam"DOESNT require notching of the bottom of the bore,the eagle h beam DOES....
btw..if you are lookig at going low 11's...dont bother with the i beams..get the h beams...crank wise,the cast crank should be fine....but for another 500 bucks,you will never have to worry......just my opinion,but do it right the first time and you will never have to worry.........ask me how i know........
