I just budget built a 6.0 that is around that HP, I bought used and redid top end. I have a 2.68 with a 79" 3 bld R it is on a 14' Alumitec runs fairly well. It is certainly not purpose built, might blow-up tomorrow. Had a stock 5.3 that had 113K before it was on 2 different boats over 300hrs o...

I run a 14' alumitec/airgator. Just put a 6.0 (maybe 400hp) on it and I run a 79" 3 bld R with a 2.68 stinger. Runs good way better than my stock 5.3.It is carburated for now FI after fishing season Yes you need the adapter or a dished flexplate. JW Wheel and TCI make several differnt options.

Very Nice

The 2 Edelbrocks I had both required a little clean-up to mount correctly. I would have the exhaust crossovers welded and the plenum welded -up. Then have it surfaced. I also made a sheetmetal gasket for the exhaust crossover port to go on the head side of main exhuast gasket. Helped keep less expen...

A buddy had a Lacey Everet built 0470-13 with 520 cylinders, lycoming rods and a few other changes, thing was an animal but was not really for cruising.

I believe that motor came out of a military observation plane Cessna Bird-dog ??

5.3 and 6.0 vortec from 2000 on are Iron Block Aluminum heads LS1/Ls6 (5.7l), LS2 (6.0), LS3 (6.2) LS7, LS9 and LSA are Aluminum block and heads, about 100lbs lighter. also LS4 was all aluminum 5.3 for a front wheel drive. Swamp the LT is much like the gen 1 SBC very different than the Gen III/IV LS...

Go to holly's website and look at the Pump arm for the 50cc pump and see if that is what you have on your carb. The pump size is like that holding tank for fuel needed at acceleration. https://www.holley.com/blog/post/carb_class_giving_the_bog_the_boot/ Explains the the 3 main parts of the pump and ...

Too much coffee I guess Double posted

I was worried about the EFI wiring but have help 2 buddies build EFI boats for the gulf. and my next one will be EFI. Take a pic of Acc. pump looks like 30cc. I am with Deano 50cc pump and bigger jets. I ran the 74HP jets,so a 500 would definitely need a little more fuel. Also the correct pump cam. ...

I had a ski nautique that the switch shorted in a nasty storm. Was covered, storm blew a limb down that went through the cover. Woke-up to what i thought was a tornado coming. BTW it was the middle of the night. Made family get into the safe room. I kept hearing it and thought it was a repetitive so...

I had High compression .020 over 472 and a cam. The 500 holley I ran had 74 High flow jets, 50cc pump and 6.5 pv. Ran very well. I tried Holley 650, 750 and 850. Also tried 750 edelbrock. All of them ran about the same when dialed with an A/F meter. None were really better then the rest when they we...

I just put a "y" connection right at the tank with a vent coming off 1 side and the return coming in the other side. I have 1 boat the has been running like that for a bout 5 years. I did turn the vent hose down and put a small screen filter on it.

The LS platform is a very strong running motor. The only issue with the LS1 is it can not be bored list the other LS and Iron Block. I have helped several buddies put boats together 1 has over 600 hrs after having 113K when wrecked. Did 1 stock EFI, 1 Holley system and 3 carbed. These engines do not...

I used a combination of a SS spring holder and a quick release. Welded the SS bolt to spring holder and used grinder to cut it down to fit in push-button style quick release. Now have quick release and flag flexes back with no issue and flag can't slide through holder. Had it for over 5 yrs. Got tir...

Ran a caddy for 10 yrs
It had old 72" 3 bld H series on my 472 was .020 over with a comp cam and 500 Holley 2 brl turned 2900 at almost 3. Ran good for what is was but man that prop would make your ears bleed.

My experience is if you have a slight concave in front of the transom and bolt/ screw or rivet it tight to the hull it will act like a trim tab and force the nose down.

Got a buddy with a 13x8 Alumitec and 5/16 poly with a 520 and SS rigging. His boat runs very well. Light enough for one person to move the nose unless it is in a bind. Fun boat to drive. We have taken it scalloping in the gulf a few times loaded and it still performs good.

Curtis have you tried stainless bolts? They are softer tend bend some before they break. My old caddy was breaking grade 8 bolts went to a softer bolt and it would at least bend before it broke. also make sure the mount doesn't have a bur or something not allowing the mount to sit flush. Do you know...

Yes there are a few of the white performance pieces around my area all run great. They are a good source for parts as well.

Some motors also required a tach reversing adapter. It would be on the motor side of the tach cable.

I ran a 15' x7-6 rivermaster with a 472 of about 6 years I had no problem crossing short stretches of dry and could pull up and get off of the bank. it took WOT and a few rudder shakes to get it moving. Put it in a bind and you were done. Caught a lot of redfish of that boat. But I spent a lot of ti...

Title was "The Budget Build" author was crowhater written in Feb of 07' I believe the stoker kit came from Ohio Crankshaft. After looking that must be the one you found I seem to remember him listing the parts somewhere. After looking at ohio crankshaft there Super Kit 496 is 2049.00. Al l...

Look up a post by Crowhater he did a 496 budget build with a complete parts list. As I remember it ran very well

I know you said 350, but after my experience with Caddy's and Gen 1 350's Get a LS2 or 6.0 truck motor and change the cam and springs and you're at your goal or over it. Have to do a lot more work to a gen 1 or 2 350 to get the same performance. If you keep the ZZ4 I have a JB Heavy duty flex plate ...

Well I run a 5.3 out of a truck with 113K put it on my buddy heavy 14' Alumitech deck-over 2.55 with 3 blade maximus, loaded with 3 people for fishing in the gulf take 3,600 to be on plane we run some nasty stock pushing hard. Took the motor of after putting about 300hrs on it. Then we put it on my ...
