N42 head

[jbuenviaje]

how much does N42 head cost..if just out of an running engine??

[jbuenviaje]

how much should i pay...hes asking for $250

You could probably get one out of an engine that wasn't just running for $100 or $150. The question should be how many miles are on it. If it needs a valve job because it has 80K miles, you might as well start with a cheaper one.

its has 160k miles on them..compare to P90 which is better/performance/easier to modify..and which block (N42 or F54) should i use..

[jbuenviaje]

will be running SU's from Ztheraphy..plus is it a good idea to use my '73 240z crank and rods to L28 block..to maintain a hi-reving engine like the 240's???

Those are some big questions. I would suggest you take some time and search and read, search and read. And when you've done that for about a week, do a little more searching and reading. Try searching hybridz.org too. Lots of good info about heads over there.

$250 for a head with 160K on it is too much in my opinion.

Where would you get the pistons to make that combo work? There is a 5.3 mm difference in stroke as well as a 3 mm bore difference between the two engines. Jon is right...you need more research.

that's what i though a little too much..will make an offer for $100..

yah.. i need to do more research..

Don't forget about the bronze valve seats depending on what year it came out of.

[jbuenviaje]

it came out of 1976..they said the block N42 also is good to use on stroker motor..due to thicker better metal than F54

[jmortensen]

That's true.
