1700 engine formulas

[Fritter]

Can everyone post up their favorite 1700 engine parts combo and horsepower numbers?

I'm thinking I want to build a Engle 130 1700 with dual Webers and about 10.1 compression.  This will be a street/strip motor, mostly street, not daily driver, just a hobby car.

I read all the very technical stuff in the archives here about the high HP 1600's and such (very impressive), but I just want to use off the shelf parts.

 mIke, I think youve answered your own question...1700/130/10:1/ HOLD ON....    I would be glad to assist you in some info when ready...little secret>spend some consideration on some NICE heads.....     small engines ROCK..!!  good luck, Dyno Don     fyi/ I know of a few old school bug in sources with aluminum barrelled standard and or slipper skirted 88's ....?

Very interesting... I am building a 61.3 x 94mm (1701cc)  motor as a project engine. I hope to get over 200 hp with some serious rpm. The sound of a little screaming mouse motor beckons...

Good luck with your project - keep us updated with your progress please 

Regards, Matt

The motor that started it all for me, Dave Chadek's 1702...64 BERG BPed 40 hp crank and 92's. He had home-made D port heads, IDA's, K8 with Siggy 1.5s... and it made 160 HP... I have to say though, he was at 12 to 1 with octane booster...YUCK! but he lived in Reno...

Mike, port velocity is what you're after with a 69x88 mouse motor.  A W130 with nice set of welded 40x35 (or 37) heads, IDA's and 1 5/8" merged exhaust would rip!  With your car I'd scout out a set of quietpack merged mufflers to complete the traditional cal-look "look".  Toss a mag on there for ignition and you'd be rockin!

My last one was mild, loved it. Next one will be pretty traditional, already have lots of parts... 110 cam, 1.3 rockers, 041's with 35.5 ex, 1 1/2" Four Tuned, 010, Crown alloy flywheel, alloy pressure plate, 10:1ish and of course IDA's on Deano manifolds ziiiinnngg!

88 x 69
Crawford's stock valve 35 x 32 ported
Web 110 with 1.25
8.8:1
40IDFs with 32 chokes
1-5/8 merged
6lb flywheel

in stock '65 with bumpers, steel chromies and 195 radials it went 14.71 @ 90

Someday I am going to make a 1700 with K8, small D ports and 48's

Jim, that's an impressive time for a stock bodied car with a relatively mild motor. Great result  Matt

Wow this is a good time!

What about this one....maybe a 125hp motor?  Good for street driving and scaring people at the strip?   

69MM counterweighted crank
Aircooled.net slip in (at the bottom) 88's with thick 92mm tops
Engle 130 cam (.524 lift with 1.25, 308 advertised duration)
CB Los Panchito heads (these keep flowing all the way to .600 lift, 168-174 flow between .500 and .600)
1.25 rockers
1 3/8 extractor, with dual QP's and stock heater boxes (this may limit somewhat but I want to keep heaters)
Dual weber DCN's
Stock fuel pump
10:1 compression (dynamic compression would be 8.17 to 1)

My Puma motor I just did...72 (offset ground 69 to Chevy) x 85.5 = 1654...35 x 32 040's ported and polished, Hemi chambers, 9 to 1, 6mm stem valves, and Ford modular beehive springs. Ti retainers, AL pushrods, CB lightwt lifters, WEB 122 (.508 x 288) 44 idf's with 36mm vents, and a 1 3/8ths step header. 115 HP and 108 torque... and it goes to 7,000...14.66 at 90 spinning all the way through 1st gear.

That's pretty cool, Joel.  Kind of a bizarro combo!  72 stroke?  How much HP do you think it would go with more cam and compression, with the stock heads?

[Joel Mohr]

If I got the compression up to 10 to 1 I bet it might make 120/122...and the numbers were belt on, through a muffler...

[70slooker]

Wow! I'm in the process of finding parts to build one of these puppies! I would love to hear of any feedback on the thin/think top 88s in theory they might work well!

DYNO, if no one hits you up about those 88s pm me some details I have been wanting to run some KS 88s real badly!

[dyno don]

  87mm slip ins are MAX...88 machined ROCK... reminds me of when I bought a cheap 67 years back in 1977  with slip in 88's and drove the car from Bishop to garden grove with my foot to the mat and I think I averaged about 78 mph all the way home and parked my new ride and went inside for a beer and came back out about 45 minutes later only to see a nice pool of oil underneath the engine. Upon closer inspection had notice that the case had cracked from #3 top to bottom from the heat and detonation/LOL...  I later that week traded my 'NEW' 67 to my friend Steve Sims, who had worked at Bergs, for my very first and most Famous (Valspar primered gey) Notchback...(have owned 12). Havent bought,sold,or driven a 88 slip in engine since..!!

[Fritter]

The "new" slip in 88's from aircooled.net are different from the "old" ones....the new ones have a 92mm register at the top, they are only machined thinner at the bottom to fit in a stock 1600 case hole.
