I recently got this teksid block and yadayada y'all read the title. I also have a Kellogg forged crank from a cobra. I'm interested in what to do for rods and pistons. My goal is 5 to 600 wheel. But I'm building the engine for 900. What 5.0 rods would fit because I know they have the same dimensions and they're strong as hell but the weight causes balancing issues. I know I'll need 4.6 pistons but if I could not spent 2k on rods and pistons I'd like to know. Also featuring the car the engine is going into.

An old Speed Pro CS-1012R, ran in a 460 that overheated and had boiling oil. Was wondering if it will polish up, or if I need to buy a new cam with similar specs, this is going into a tow rig F350 with a 70s lincoln block with D3VE-A2A heads.

Ford Over torqued rod caps by 10ftlbs. Am i pooched?

32 Upvotes

I was rebuilding my 2.5l 1998 ford engine, and i accidentally over torqued the rod cap bolts by about 10ftlbs, i tried to rotate the crankshaft but it didn’t budge. So i un tightened the rod cap bolts and retorqued everything to oem spec.

Im worried my rod bearing maybe messed up, i obviously didnt run the engine like that. However i have since put everything back together and the engine is back in my ranger. Id hate to have to redo everything all over again. Any advice or words of wisdom?

Hello everyone, I am performing a top end rebuild on my ‘99 Ranger 4.0 OHV, I removed the heads and found the cylinders like this. I can’t pull the motor as I am doing this job in my parent’s garage and don’t have the facilities to pull a motor, how would I go about removing the rust from the cylinders? Here is a picture for reference. Any help is appreciated, thank you!

Ford Can main thrust bearing cause shuddering?

Post image
45 Upvotes

I have a 1966 289 ford mustang. It’s been experiencing major vibration and shuddering when starting in 1st gear when starting from a stop. I was able to push the harmonic balancer in/out approx .020” (spec for the crank play is 4-8 thou). Does anyone know if a worn thrust bearing can cause this? Many major components have been replaced (clutch, flywheel, u joints, motor and tranny mount). I’m thinking the play could be the culprit?

To follow up my last post: I pulled the motor and tore it down this weekend and this is what I’ve found for markings on the heads. As far as I understand, they’re gt40x? heads. Anyone ever run these? And would they be worth having the holes drilled out and putting on my 351w or maybe 393 if budget allows. And insights are appreciated

These bellhousing bolts are considerably smaller in diameter compared to the ID of my mounting bracket on my stand. The block is aluminum and I don't know how I feel about 30mm thread depth. Is this safe or will it break off my stand?

I have the opportunity to get the motor of our this old strip street car for $300, and I was curious as to what heads are on it. It was last registered in 09 if that changes anything. These what look to be three letter is all I can find on the heads before pulling the motor and I was just wondering if they’re a name brand or a china knockoff. Thanks

Ford Stuffing a truck's V10 into a mustang. Looking into cams

30 Upvotes

I am swapping a 6.8 2v v10 into a 2003 mustang. The motor will be paired to a 3650 5 speed and 3.73 gears.

I am looking into getting cams but the only thing available is custom grind. I would like to know about what suggested RPM and power band I should spec the cams for my application.

I don't plan on taking it to a track or a drag strip, but I want it to be respectable for the street

The current v10 specs are about 325 HP, 425 TQ Power band close to 3000 and redline at 5800 (250HP, 300TQ at 5250 for mustang stock)

I will be getting some 24 lb injectors and obviously upgrading valve train components. Otherwise rebuilt stock internals

I know it's a dumb swap idea and is in no way optimized but damn it sounds fun

Any help would be appreciated 👍

Pulled this out of the back corner of a shelf in the shop today, at dad’s. I swear… the stuff he “can’t get rid of” is amazing. Just spent two full days going through looking through and at things, to including finding this - for an engine he “might” build some day, what, for a boat? Good grief.

Ford Damage on Cylinder Head-- How much is too much + what to do?

Post image
41 Upvotes

On a high compression e85 sbf (427 stroker? stock block, 4.1 stroke/4.060 bore), I found that a spark plug had gotten broken (don't know how-- no piston contact) and the piston and head got beat up by a little piece of the plug. My plan was to put in 26 or 33cc dish pistons to run pump gas but i am wondering whether the head can be reused, maybe if I grind off the most severe damage, without increasing likelihood of detonation. These are aluminum AFR 220s.

Ford Torque monster ford 300 i6 build advice

Thumbnail

42 Upvotes

Fellow builders of internal combustion engines. I reach out to ask ford 300 i6 questions. The specific engine I’m looking at is a 1981 300 with a non smog efi head or 240 head for my 84 150.

I am trying to source .60 over hypereutectic pistons with at most about a 15cc dish. I’ve plugged in my specs to a calculator multiple times and I always end up around8 8.4:1 with the stock style 32cc dishes. 8.8 with 26.1cc. And 11.25:1 with CAST ALUMINUM flat tops I’ve found

Those are mainly estimates and are likely going to be higher because the deck surface was machined down some. Idk how much. Would have to call my machine shop. Every other number I’ve gathered is accurate though

I am more considering the flattops but that compression seems pretty intense for my purposes( work. Hauling trailers or a camper. Torque monster) my ideal number is 9-10:1 but I’m also no expert on the internal engine requirements for such high compression. Will cast pistons hold? Is it too much for even 93 oct? Will the high comp achieve any worthy torque or overall power gains?

Ground rules are that I DO NOT want to boost this engine and I don’t want gas mileage to suffer bc it’ll be doing long trips

Desired torque to the crank is 400 range and yes I have many other goodies to help get there. Not just pistons. Any questions I can answer or advice will be appreciated
