    Default '87 Taylor LP build... help.

    Just joined the forum, been reading and searching on here for a while though, might as well get right to it...

    Ive got a 1987 Taylor LP, 454 (not sure 2 or 4 bolt as i havent pulled the motor out yet), berkely jet (not sure what model or impeller), and im looking to make it alot of fun.
    Im quite ignorant when it comes to V8s and even more so jet powered marine motors so Ive come here for some good knowledgeable guidance. Ive built one harley motor and squeezed 123hp and 117ftlbs out of two cylinders, and that's on a 630lb bike so needless to say its fun. I want my boat to be just as fun.

    The boat is going down to bare hull in november. I plan on making sure the floor amd stringers are in perfect order, she will get new paint, interior and electronics. So if there are any pitfalls or areas that need special attention Id love to hear about them.

    Now to the motor... Id like to build a 468 or 496 (havent decided yet) blower ready and
    squeeze 550hp out of it . Then after I have assured the motor is broken in properly and have had a chance to save up the cash Id like to put a blower on to really top it off. Also I REALLY like the look of a tunnel ram and two carbs with tall arrestors sitting ontop, just not sure how well they would work for what i want.

    Reliability is important, I dont want to have to pull the motor twice a year to fix issues. Now I wont be racing this on the weekends but I love goin fast when I have the chance and my father has a 25' Baja outlaw sporting a 502 and Id really like to be able to flat walk away from him.

    Any and all advice is greatly appreciated, I know its hard dealing with us newbs constantly. Also of anyone has a build like Im thinking of Id love to read your specs.


    Thanks again in advance,
    Friends call me Ross

    Taylors were not made to go real fast! 85 MPH is doable but you can get into some handling issues at top speed and shutdown! A friend of mine just bought one and with about 550 HP it is running around 74-75 MPH with good handling and smooth operation! Don't get me wrong Taylors were well built solid boats!
    550 HP out of a 454 + cubic inch is very easy to get and if you were to step up to around 600+ I think you would like it more and not have to add the blower or TR to enjoy what you have! But the cool factor would be down a bit! Good luck with whatever you do!

    A little more info.

    If it has a Delta pad, with an insert pump, it gets hairy above 70 mph. They can go faster on 550+ hp, easy 60-65 mph on stock hp.

    Ok lets say I want to shoot for 85 mph, using a 468 rotating assembly from either eagle or scat would you guys suggest cast or forged crank? Id be shooting for just under 10:1 cr, eagle sells an assembly with cast crank, forged 18cc pistons and 6.385 H rods that would put me at 9.95 ish cr with a head thats got around 120cc combustion chambers. Id want to go with a weiand TR and two 750 holleys.

    Now having said all that, could anyone recommend a set of heads and cam setup that would work well with that and get me a good bit into the 600hp range?
    Or should i bump up to the 496 rotating assemblies?

    IMO 85mph in an LP i going to be real tough, i would PM cstraub or steelcomp about head and cam recommendations. If u get that LP in the 70s, you did something.

    All these questions should be directed to who ever your engine builder is, or is going to be. If you were going to pull an old 454 out of a Suburban, take it to the local machine shop for a valve job and replace the rings and bearings, you could pick about any mild cam out of a catalog and be on your way. If you have a HP goal, or a target for your motor to achieve and you don't know what the best parts combination is, or this decision is little more than your experience level. Do yourself a favor and get hooked up with a builder who does this daily. You will save yourself time, money and headaches by paying for their knowledge VS sorting through a bunch of opinions obtained from the internet. There are some very good builders that are active members of this forum. If you get someone to build you a long block, trust me you'll still be very involved in the build and probably learn a lot more about engines quicker and cheaper than going through the school of hard knocks on your own.

    IMO, you're looking at more than a pump gas NA 468 or 496 to get your goals. Check out Alan's LP, 632ci to get 80's.
