thx for the VIN decode robot, i found that the 3970010 castingn° could be from either a 302, 327 or 350 depending what site i looked at. Overhere they said they ripped me off and sold me another 305. (see what i mean by those backyard "pros" here in holland). HP wise i was thinking to go about 350 as they used to say one HP per cubic inch so your right on the money scooter.
@ techinspector1, right now i haven't made any decisions on parts, i seen alot of talk about the later vortec heads, but would they even fit my block as its so old?
and as its been more then 6y since i been to a meeting with my own vehicle. I would just put new gaskets and new cranckbearings init for this season and start gathering the needed parts so when the season ends i pull out the engine for a complete overhaul. So theres no rush.
Keep in mind that US parts cost about double (sometimes even triple) the price you pay in the US (shipping and customs) so i need to save up a little more then normal.example i just got a enginetech gasketkit thats about 45usd i payed 80€ (about 120usd) what still is a fair price overhere.
Thats the reason i'm taking it easy buying stuff untill i see a good buy here or in the surrounding countries(no importtax then).
Theres some things i will do either to make it run more reliable or to get back a few horses.
-put an adjustable electronic fuelpump in the tank
-electric cooling fan
-oilcooler for the engine
-oilcooler for the tranny
-use two old airfilterhouses to make one with a double intakepipe and use a flexhose to get to the grille to make some sort of ram-air system
-change the front suspension for one from a chevy g30(stiffer)
-use two flexhoses from bumper to the backplates of the frontbrakes to get forced cooling on the brakes.
-lose the ugly sounding glasspack cherrybomb for a flowmaster deltaflow 40series and some descent headers
most stuff i allready have from friends
