Theres a coolant passage that needs to be plugged or opened on the deck surface, I dont remember but after that they will bolt down. You will need to use a 2v timing cover other wise yes to the rest

 

thanks

 

You could also buy the conversion kit from Logan Motorsport and just put the 3v in. The conversion kit allows you to use your stock wiring harness, ecu, exhaust, etc.

 

not trying to sound like a d!ck, but isn't those kits are meant when going from 2v to 3v (head-wise)? Op is keeping his 2v heads and running 3v short block... only the bottom-end is gonna change... eh?

 

i belive you have to drill the driver side front water port but that is not hard. also there is no provision for a bolt in the timing cover so it has to be filled with rtv.

 

3v heads arent exactly better

 

Everything I've read says that they flow better. Almost as good a 4v heads.

 

got a feeling he prob found a short block for sale with out heads etc and wants to use that with his current parts.

3v>2v stock to stock and ported to stock. The stock 3v's flow around 220 on the intake stock, thats around what most ported 2v's flow.

In the end 4v>3v>2v

 

correct 86er a boy has a 4.6 that came out of a junkyard and put forged internals in it .had it blueprinted and balanced its bored 20 over and just happens to be a 4.6 3v . he totaled his car and he is selling me the motor tomorow for 1500 . its just the shortblock and if you all can paint a pic for me showing where to drill . that will help. im staying 2v cause im getting ported heads and getting jim from mr.norms garage to grind some blower cams and hit 530 or so with this little v-1 s-trim . then when im done ill just throw the intake and oil pan and accessories on it and go . goal is next summer .

 

If you lay the head gasket down you see the hole and where it needs to be drilled

 

3v's have bigger combustion chambers so i would find out what cc the pistons are. stock slugs for a 3v are 14cc which will is fine for boost and na, but if it was built for na odds are the dish is real small.

 

thanks im going to pick it up today . guys said they are ither 17cc or 18cc diamond pistons
