horsepower guess

[MPac]

thanks alot the transmission in there is an old th200. i was thinking the best way to go would be to go find a th350 and do a stock rebuild with a shift kit like mpac suggested.

It would be alot easier and cheaper to go that route. Also if you do go with aluminum heads you will really shoot up big time over 300 horsepower. BUT there is a couple things you need to watch for with aluminum heads. The nice thing about aluminum heads is you can get a way with more compression on pump gas then you could with cast iron, also you get a nice weight savings. Just an idea of the weight. My RHS aluminum race heads are 19 pounds a piece. But with aluminum heads they are alot easier to warp if your not careful. Also with some aluminum heads you need to double check the toquring spec when bolting them on since aluminum is softer. Over all I think if you looked on craigslist and found a nice set of vortecs for about 250 to 300 then went through them you'd probably have 500 dollars tops in them and be well over your goal. Or if you want to go with aftermarket with a good brand and a cheap price.

well im gonna go with some new aftermarket cylinder heads. and i think im gonna have to mark vortecs out of this one though cause i wanna keep my edelbrock performer rpm manifold. also anything i should know before i do this transmission swap because that is what im concentrating on right now.

AFAIK it's a bolt-in swap. Choose a stall speed that compliments the camshaft. Don't get greedy and go straight to a "stage 3" shift kit.

 

[pillability]

haha no no stage 3 shift kit for me i realise this is a pretty mild build.

can someone find out some new dynosim numbers for me? i found some aluminum dart shp heads on summit that im interested in.
displacement: 355
type of cyl. head: dart shp aluminum 180cc intake runner 64cc chamber
valve size: 2.02 int. 1.60 exh.
comp. ratio: 9.5:1 maybe
carb. size: edelbrock 600 cfm
manifold type: aluminum dual plane
headers: hooker 1 5/8in. full length
cam/lifter type: hydraulic
lift: .429 intake .438 exhaust
IVO BTDC: 17
EVO BBC:64
IVC ABDC: 49
EVC ATDC: 18
duration: 246 int. 263 exh.
overlap: 34.50 degrees

that cam is kind of small. my guestimate of that set up with be in the 300hp range.

I was running a .480 lift and was getting around 350-375 from the research i had found

Care to do mine?
1966 Olds 333 (bore 3.958", stroke 3.385")
10.42:1 CR
Engle JM 22/25 H cam (.512 degrees intake lift, .523 degrees exhaust lift, 230 degrees intake @.050, 236 degrees exhaust @ .050”, 110 degree lobe separation)
Edelbrock 750
Edelbrock Performer RPM intake
1 7/8” headers, full length
Stock heads, massaged, 3 angle valve job, 60 cc heads
IVO BTDC: 8
EVO BBC:52
IVC ABDC: 42
EVC ATDC: 4
( I am going by my cam card, but the valve open/close doesn't look right compared to the other posters?)

Hopefully I didn't leave anything out....

im pretty good with SBC.... no idea on others especially olds motors.

 

[pillability]

yeah i realised it was kindof small but as long as i get in that range ill accomplish what i wanted to.

386hp @ 6000rpm
374tq @ 4500rpm (above 300lbs from 2000-almost 7000!)
This thing has a beautiful power curve. Probably loves to rev but still has really strong low-end torque
