So here is my project and we all know there are plenty of ways to make hp/torque, but this is the project for me right now. Basically, a spin off from another 1679cc build that was posted years ago, but the premise with this combo is to have a bit more top end and wider power band. The other idea is to use some of these parts to mate them with a new short block (84mm, 2044cc) and maximize the top end parts at a later date e.g. carbs, heads, exhaust
Anyone want to guess what my HP/TQ will be in the end?
1679cc 88mm slip/machine in
L5 40x35.5 heads dual springs
FK44
1.4 rockers
weber 40mm idf carbs
1-5/8 A1 exhaust
9.5cr
total seal rings
lightened fly wheel |
Good day.. Been following this post.. Is this a no machining build? Coz i have a 1600 dual port that id like to beef up a little bit.. And given the limited choice of parts found here in the philippines, this is the type of build i will be needing.. Could you post aside from the parts, brand of manufacturers so i could do a some parts finding.. Thanks! |

Again...dont think it is a wise move to run those pistons(~590grams) with a FK44. That engine is gonna rev as high as you want it. My 2276 with a FK44 will rev to 7400 no problem.
Also make sure your heads will handle the .560-.570 lift.
Third...I would run Jaycee Pushrod tubes as you will need the clearance.
Fourth.... I wouldn't worry with a svda. This engine won't like anything under 2800 rpm. Doubt very seriously you will make 6-7 inches of vacuum...
It's gonna haul no doubt, but I think your power range will be narrow.

I would drop to a FK42-43 due to the engine size. It's still going to rev to the moon.
Find a set of Mahle forged 88s and run those with the Thick Wall AA barrels. Sell the unused stuff.

I dont understand a no machine build.unless you have all new parts that need nothing. but Ive seen tomany nomachine builds done out of crap thats wore out and being done by a scamer/useless/exspert and charging for a good properly well done job to an unsuspecting buyer.... getting screwed. just my observations. yes you can rebuild a motor without going biger& better. just make sure thats what is wanted and it can be done satisfactory...witch is a very broad term.  |

Correct...that's why I do a lot of research and ask as many people as I can and most of all..do the work myself. |

I hope to get my 1679 dyno'd when I get it together. Probably have to do a chassis dyno'd around here tho. Between you, astro, and me we should have some solid info on three different same-size builds.

yes, I'm committed more than ever now...basically it's a challenge at this point. I had no idea sourcing forged pistons would be so difficult. |

it's a lot easier if you simply go to 90.5, 92, or 94mm.

I just got a pm from a member about an nos berg set. If I don't get them you might be interested..he didn't have cyls but john@aircooled sells them. Reason being my engine would probably do fine with the aa's as I have a lower powerband. Let me know and I'll send you his info.

Why is it easier to go with 90.5, 92 or 94 mm rather with the 88mm? |

He wants forged Pistons for the weight, and they're hard to find in 88mm.

A friend of mine builds formula vee engines , he built a 1640 with standard valves ,standard crank ,rods etc . 5/8 F Vee exhaust and a single 40DCN ,
I think it runs aftermarket rockers with a local aussie cam grind , single valve springs . It dynoed at just under 113 WHP with fan belt and pump fuel .

88mm forged pistons stopped being available a couple years ago, while you can still buy 90.5-94mm new now.

| Another newbie question... How about for the trans? Would you still be able to use a stock tranny for this? |

I'm going to. It didn't break the original never-touched '64 4.37 trans with the old combo that made more low end torque, but I wasn't doing redline clutch drops either. I did do quite a few 2.10 60' launches on 165's, not hard enough that it wanted to break loose. Should be fine with a bigger cam that moves the torque band up.

I am as well but im building this engine for midrange and not goin to be drag racing. If youre trying to bust them they will. Quick like.

DBO, is this build still a go? I see some of your original posts have been deleted.
I too have been collecting parts for and planning a 1700 (1679) build for a while. I have been back and forth on heads and cam. I have been watching the astronaut's progress closely as well. This is my current plan; I have everything but the heads.
Mexican AS41 case .020 line bore
Welded 69mm c/w crank .20/.20
Stock weight flywheel balanced to crank
Stock rods
Web 163 cam
AA t/w 88 P&C set
Tims ported super stock heads
Dual 40 dells
1 1/2" scat merged header
Will shoot for .040 - .050 deck and around 9.0:1 CR
Have 1.25 and 1.3 rockers that can be added if needed.

I think you will have a hard time getting close to .040 deck with those pistons. You may need to machine the barrels a bit to dial it in.
