RECO2 CLEVO

[CHESTNUTXE 7,312]

yeah but lets leave that for another thread,lets concentrate on the 02

[CHESTNUTXE 7,312]

Looks like i will have to bite the bullet and get the block bored and new pistons sp555 060 around $300,rings $70 and $300 for the bore and hone ,may as well chuck some cam bearings in there as well ,oh and some bearings $140,so we are looking at $900 odd.

[CHESTNUTXE 7,312]

finaly got the paint 

[CHESTNUTXE 7,312]

i new that spare rocker cover would come in handy

[gerg 10,871]

Wow those throats in the manifold are pissy. The one off my coupe didn't have those, just straight holes, and it was a 302.

[CHESTNUTXE 7,312]

Yes these 2 barrel manifolds are very rare and only came on the 1974-75 2 barrel 351c with red rocker covers and a 2 barrel carb,ford was looking for better fuel consumption so i have been told,check the dominator style adaptor lol.

wind testing tunnel

[CHESTNUTXE 7,312]

parts all lined up and ready just waiting on what to do with the block

[CHESTNUTXE 7,312]

another thing to watch when soughting out the waterpump bolts is 2 have a factory style washer on them so when you do the bottom alternator bolt up no water leaks out of the bolt maybe put a little sealer when doing the bolt up,because the pump is alloy you cant do em up to tight otherwise they will strip easy.

[CHESTNUTXE 7,312]

Today just painting the bolts

[CHESTNUTXE 7,312]

just got the gasket set ,and 2v intake set.

[CHESTNUTXE 7,312]

The carby came back as well ,fully serviced ,375cfm.

[CHESTNUTXE 7,312]

But the best thing of all today is i solved the block problem i bought another clevo lol 3rd one in 3 weeks but this one is 351 short motor.

[CHESTNUTXE 7,312]

i thinks its another 77 cast date 

[CHESTNUTXE 7,312]

and she has the lip for the 4v valves

[CHESTNUTXE 7,312]

so now comes the decision to keep the 351c crank n rods or keep the 302 crank n rods at 040 ,im intending on selling the engine when finished so i might keep the crank for the std bore block and use one of the sets of 302 rods and get the hypatec short pistons for the 6'' rod combo.

[CHESTNUTXE 7,312]

by 3.40 i had the whole short motor stripped,even the core plugs and oil plugs

[CHESTNUTXE 7,312]

351 rods n pistons

[bear351c 10,270]

No mucking around here............ 

[gerg 10,871]

Is that a locally cast crank? I don't recall 4MAs having "351" cast into them. If so, how do the local cranks rate vs the 4MA (nodular) units?

[Thom 6,651]

From what I've read the local cranks are equivalent to a 4ma but not quite as good as a 4mab but you are correct gerg it is a locally cast crank only the Australian cranks had their size cast into them the US version were either 4m, 4ma or 4mab

[CHESTNUTXE 7,312]

Just local cast crank ,circa mid 70's,the normal 351 crank in the usa had 4MA cast into them and 4MA-B for selected models,but the whole argument for 45 years is the std crank is proberley as good as the 4ma-b,all of them are good to around 450hp

[CHESTNUTXE 7,312]

this is a usa 4ma in my pillowblock 351

[CHESTNUTXE 7,312]

I took the block down to the machine shop and it checks out for reco,hot tank or acid bath ,hone,cam bearings,and welsh plugs.Then we can decide if we are going to use the 351 crank n rods or keep the build as a 302.Keeping in mind we are using the closed chamber heads ,might be a bit stout at 10.7.1 with the 351 combo.

[deankxf 20,292]

bigger cam fixes higher comp doesn't it.. 

can relieve the closed chambers a bit also, need to remove the sharp edge anyway ..
