Any tips on pulling the main bearing caps?The fsm calls for a C3059 removal tool, but there are none to rent.I punched out all the freeze plugs in the block and it was full of this grey sludge.Maybe I should just pull all the pistons and the cam, then send the crank,block and heads to the machine shop to be checked out.I do want to do this correctly, just don't have thousands of dollars to spend.I have posted a picture of the back of the dampner...it is ruined or salvageable?I did find mention of the "Maltese cross plus X" stamped on the engine pad,in the FSM and will alert the machine shop. Maltese cross and X are factory undersize crank

I think alot forget what we used to do and had a heck of a good time doing it. That may be true, but we have different fuels today and different expectations.

The head gaskets make me uneasy because I don't think they're stock, meaning someone has been in the engine before.
Someone's been in there before, no doubt about that. A set of TRW 2355's would bump up the compression and weigh close enough to stock pistons that you could think about squeeking by without balancing. They would be a good choice if you were looking at an aftermarket closed chambered head. A rumpety cam like that hughes whiplash really has no place in a truck with efi and a low-cr engine.

Pulled the pistons last night and cleaned the bores.The ridge isn't as bad as it looks in the pictures.The crank journals look perfect and the rods seem ok although 1 is a bit tight.Will get the taper and wear measured by a machinist today.Do you guys have any other recommendations on what stock pistons would be best for better compression?I am going to try and find the best used set of pistons I can to save money.Thanks! You have to have the ridge removed if you want to put in a taller CH piston in there, otherwise it might break piston rings.

I stopped into the machine shop today and got good and bad news.The block needs to be bored, but everything else is in really great shape.The crank is not undersized as the stamping indicates and the heads have already been done at some point.Valves and springs look new, seats were all good and guides are all within spec.Now I need advice on which pistons to get.1978 stock silv-o-lites, 1967 higher compression 350NP-30's, KB184's or maybe speedpro forged....I don't know.Will get new stock pushrods and the stock rockers look fine.This is all about budget.I want a nice running motor, but not a dog.I need low compression cam advice too!

What would the specs on a proper RV type cam be for a motor with around 9 to 1 compression? Sorry for my ignorance on cam selection.Falcon has this cam for $85 ...any good?

I am leaning towards the Speed Pro L2266F30 set with Hastings moly rings for around $395 @ Summit. I can get a set of 350NP-30 with iron rings @ Falcon Global for $315.Is forged with moly rings overkill on a stock low budget rebuilt motor? yes overkill, this is a low RPM truck torque build. I would suggest some eBay cast cheapies/moly rings or kb hypers (which are way better but more $$) and you need more compression which the KB's would give you & you likely could get quench if you go with some aftermarket closed chamber heads & carefull measureing & as said heads are gonna be the big expense on this as rebuilding a set of iron stockers can approach a set of aluminum aftermarket ones (stealths) tho you might be able to get by with a valve job (odds ain't good) & are they flat tho with composition head gaskets you can have a bit of warp & they lower your already low SCR as opposed to the OE steel shim thin head gaskets. I would get some plasma moly rings (& cast pistons off of eBay) & after the shop bores/hones, you do a quick hone with a Brush Research Manufacturing dingle berry hone for moly rings and your bore size or have them do it (its worth it).

I think those are the flat top no valve relief pistons that have a really short compression height. Look into wisco pro tru street. Comes with moly rings and the price will be close to the 2266 with rings. here: wiseco summit Won't be zero deck but a lot closer than the 2266's.
