After a week of emailing Eagle I got 4 connecting rods and it looks like ill be using Summit as the shipping is $80 cheaper than Jeggs and the sales rep when he rang ask for 4 but didn't tell eagle that it wasn't to match another 4 that it was for a 4cyl application so tomorrow morning ill be up at 4am to make the order


PROBLEMS pistons the block I have has 30+ pistons and I checked the bore no ridge marks up the top and still had hone marks in it so bye the eye it looked good enough to just hone but I decided to go 40+ as it had the wrong pistons in it 460 smog (I think that's what you call them )
my mate rang me and said theres a problem with the bore at 40 it wont clean up I thought im stuffed now as I only saw 40+ for them .Who ever bored it machined them like funnels omg--He ended up honing the bore while I was there and the bottom of the bore wasn't clean you could still see the light glaze I said it will have to do I have no choice and finding a block here id impossible .Then my mate suggest getting the shirts coated which will give them a little more size $100 to do all 4 so im getting them done and now I need to check the ring gap when its done may even have to buy file backs of those zero rings

With the crankshaft I cant get it machined until I have the connecting rods so that's on hold to now my mate has offered to clean up the ports on my new head im not sure if I want to pull apart a new head he said it will improve the flow rate it will be done for free

I'm NOT an expert on the subject but I would be VERY hesitant to mess with the porting in the head.... there are bad things that CAN come from that such as fuel not staying atomized at low rpm (IE loading up at idle or low speed) or losing low end torque (which is vital for a boat) to gain top end and you are building a lugger not a 1/4 mile screamer..
just my .02

I don't want to loose low end power this guy is a well know engine builder here its only around the guide boss that needs a clean up as edelbrock don't touch the casting around the guide boss as it takes time and will have a affect on the retail price . I should off said clean up as people know porting as making the ports larger todays its changing the shape of the port that's important not size--that's why these new style v8 go well the heads make the power

Actually you DID say "clean up" and I knew what you meant.
I've seen it go both ways ..... Both with a "well known" fellow doing the work.
As long as he really does have a good understanding of what works well for a marine engine you are likely ok but sooo many people want to build a boat engine the same way they would a dragster. Just saying be careful mate.

I don't really want a race boat I need good idle and bottom end to get the boat on the plain with my wifes fat *** in there
lol really I want a good idle don't want it thumping when I engage it into gear or doing 5mph at idle

personally I'd most likely leave it alone.. edelbrock makes good stuff right out of the box... MIGHT be worth a call to edelbrock tech line to discuss their thoughts on your planned mods tho
